Window opening limiter comb how to install. PVC window stop "window comb" white plastic. Types of window sash clamps

Modern plastic windows managed to prove to everyone their high practicality and functionality. One of the main advantages of these windows is their high tightness. But this is also a disadvantage: the fact is that the air in the rooms must be renewed. To do this, people open a plastic window in ventilation mode. It is convenient and comfortable in summer. But in winter this is far from best option. To solve this problem, there is a special window opening limiter. It allows you to open the doors only to a small certain angle. Let's look at the main types and rules for choosing these accessories.

Limiter functions

This small accessory is a piece of hardware that is installed in the sash and fixed in a certain position. The door is open. The design of the product is a small bar with slots in it.

The window is secured using a special lock. It is also needed to be able to change the position of the open window within narrow limits - from 1 to 10 centimeters. The window opening limiter bar is called a comb. When the window is equipped with such an accessory, it will not suddenly slam shut under the influence of drafts, nor will it open due to gusts of wind.

Types by purpose

The comb is not the only such accessory. Depending on the purpose, other options can be distinguished. So, a child lock is also called a limiter, which prevents a child from opening the door.

There are window opening limiters with a cable. These accessories are designed to fix the sashes at a certain angle. Using a handle equipped with a special lock, the window will not open in the standard way - this is also a kind of limiter. In addition to these products, there are also accessories in the form of latches on magnets. They are designed for sliding windows and doors.

Types of window combs

The “comb” window opening limiter is distinguished by the materials from which this product is made. The plastic comb is affordable. Manufacturers make these devices in different shades, you can easily select desired color. But due to the nature of plastic, an accessory of this type is not very durable. Metal regulators are much more reliable, but are offered at higher prices.

At the same time, reliability is at a high level. It’s better to overpay a little, but buy the highest quality and durable product, reviews say. Combined solutions can also be distinguished. Plastic and metal are combined here. So, in some models the comb is plastic, but the retainer for it is metal. In addition to differences in the material of manufacture, the devices also differ in the type of fastening: under the window handle or at the end of the sash. Let's look at each option below.

Hand comb

These devices consist of a comb and a pin-shaped lock. The latter is installed under the window handle. The plastic comb is fixed to the stationary part of the frame. Depending on the design features, the part can be raised or lowered. In different positions it takes up minimal space. This is the most convenient window opening limiter.

But there are accessories that do not rise or fall completely. They are less practical - the product will constantly cling to the curtains and create various obstacles during the operation of the window.

The comb can be plastic, but it is better to select a retainer made of metal. Plastic products wear out quickly. When choosing, you should pay attention that the holes for fasteners coincide with those on the door handle.

Comb in the flap of the sash

This window opening limiter is installed on the end of the sash. The comb is mounted on a fixed frame. The installation location does not depend on the position of the handle or any other element. This allows you to place it anywhere. The pin is attached using a long self-tapping screw. The latter passes through two overlap bridges in the sash. Only then can we talk about reliable fastening.

Features of different limiters

When purchasing a child lock window with a key, you should find a place where the key will be stored permanently. There are high chances of losing it. If the window will partially close and open, it is best to purchase a comb rather than a handle with a lock and key. The comb will allow you to adjust a small gap without having to open the doors. Of course, the device is not suitable for families with children, as it does not provide reliable protection against opening. But it allows you to conveniently and quickly adjust the desired angle.

Cable stops are suitable for setting the desired opening angle in both horizontal and vertical planes. In this case, it will no longer be possible to open the window wide. When choosing a comb, it is better to opt for metal window opening limiters. As already noted, they are much more reliable and have a good resource.

Penkid limiters

These accessories are in good demand among consumers. This is a cable limiter. It is capable of performing multiple tasks at once. This is a window blocking to protect against opening the sash, as well as protection against illegal entry.

The design uses a thick cable made of high-quality steel. It cannot be cut simply hand tools. The length of the cable is 20 centimeters. This allows you to set the limiter at any convenient location. The door can be opened at a distance of up to 10 centimeters. The design can withstand pressure of 550 kilograms.

The Penkid window opening limiter has a good set of components. It contains everything you need for installation. This:

steel cable;
plastic nozzles;
metal base and lock for it;
key;
four self-tapping screws for installation;
installation instructions.

Conclusion

As you can see, there are quite a lot of such devices. It is difficult to say which one is better. Each accessory solves its own individual problems. But to protect against a draft opening the window, you can purchase a metal comb, and this will be quite enough. If there are children in the family, then you cannot do without a blocker with a lock.

Plastic windows have long proven their practicality and functionality. One of their main advantages is ensuring tightness. However, this can also be considered a certain disadvantage, because the air in the room must be periodically renewed. So you have to open the windows for ventilation. In winter this is not very convenient, and at other times of the year too. To facilitate this task, the opening limiter of plastic windows is intended, which allows you to open the hinged sash only to a certain angle. This will achieve a normal level of ventilation in the room.

Purpose of the limiter

You can define the device in question. Plastic window limiter — this is an element of fittings that allows you to install and fix the window sash in a certain open position. Structurally, this mechanism is a bar with slots, as well as a sash position lock. It allows you to change the position of the open window sash, usually within 1-10 cm. The strips that regulate the degree of opening of the sash are also called combs.

When such a device is installed on a window, the sash will not slam shut due to a draft and will not open completely due to a gust of wind.

Types of combs for windows

The comb for PVC windows may vary depending on the material of manufacture:

Window stops also differ in the installation method: under the sash handle and in the overlap (end) of the sash.

Handle combs

This limiter for opening a plastic window consists of a comb and a pin (clamp), which is secured under the window handle. The comb itself is mounted on a fixed frame. Depending on the design, the comb can be lowered or raised, taking up minimal space in the lowered position. This is the most convenient option. There are also combs that cannot be fully raised or lowered, pressed tightly to the frame. They are less convenient, as they constantly cling to the curtains and create obstacles near the window.

It is better to choose a metal lock for windows, since plastic product It can break down very quickly. When choosing a clamp, you must ensure that its holes coincide with the holes for the screws in the handle.

Combs with fastening into the sash overlap

A sash lock of this type is not mounted under the handle, but at the end of the sash. The comb itself is traditionally mounted on a fixed frame. The mounting location of such a limiter does not depend on the location of the handle. This makes it possible to place it anywhere. For example, sometimes there is some element of fittings just opposite the handle, so it is impossible to attach the latch under the handle.

The pin is fastened with a long self-tapping screw, which must pass through both internal jumpers of the sash overlap. Only in this case will the fastening be sufficiently reliable.

Important: This opening clamp for plastic windows cannot be installed on wooden sashes. The forces generated on the pin are such that they can damage the wood along its grain.

Setting the limiter

You can install a window stop at any time, including on plastic windows that have been in use for a long time. The design of the limiter provides for this. Especially such a simple mechanism as a comb.

Tools required for work

To ensure that the protection against opening or closing plastic windows is installed correctly, before installing the comb, you must prepare the following tools and materials for work:

limiter (comb) with pin;
marking tool (pencil);
drill with drills;
a “Cross” screwdriver or a screwdriver with a corresponding bit;
self-tapping screws up to 13 mm long. Longer screws cannot be used, as they can damage the window profile.

Tip: If you are installing a limiter in the overlap of a window sash, then additionally look for a self-tapping screw, the length of which would exceed the size of the latch by 3 cm. Having passed through the latch, the self-tapping screw will firmly fix it on the end of the sash.

Installation of a limiter with fastening under the handle

Installation of a limiter with fastening into the sash overlap

The installation location of the limiter is pre-selected. Since the handle is not involved, the comb can be installed anywhere on the sash.
A comb is screwed to the frame. For this, self-tapping screws up to 13 mm long are used.
When the sash is in a closed position, mark with a pencil the position of the latch on the flap of the sash. The latch should be located exactly opposite the comb, but at the same time so as not to interfere with closing the window.
A latch is screwed to the end of the sash (a hole is first drilled for it).
The operation of the limiter is checked.

Disadvantages of combs compared to valves

The plastic window opening regulator, in addition to its undeniable advantages, is not without some disadvantages. They must be taken into account when deciding to install a limiter if there is a choice between them and inlet window valves:

This device is not a barrier for small children. It can be easily opened, after which access to the open window will be unlocked;
If the home is on the ground floor, intruders can take advantage of the opportunity to enter through a half-open window. The comb is easily removed from the clamp, and the window sash opens from the outside;
If you forget about the slightly open window in the cold season, then there is a high probability of overcooling the room;
When attaching the sash to the clamp, the noise-proof properties of the plastic window will not be ensured;

Compared to combs, window supply valves do not have these disadvantages. Fresh air comes in moderate quantities, and the window itself remains closed.

If you decide to install a sash opening limiter on your window, then follow the recommendations listed above and take into account all the installation nuances. In this case, the stopper will serve you well long time, and you won't be disappointed.

Today, plastic windows are installed almost everywhere. They are durable, functional, and provide reliable heat and sound insulation. Increase comfort PVC double glazing, while making them safe for children and pets, window restrictors allow.

Peculiarities

A window stop is a design that allows you to open a window slightly, leaving a small gap and fixing the window sash in a given position. The device received the name “comb” for its external resemblance to a comb. It has several grooves. A rod can be placed in any of them, which allows you to hold the slightly open window in one position, and prevent household members and pets from getting too close to the window opening.

The comb is installed on turning windows, that is, on those where the sash opens exclusively in the horizontal direction. In essence, the limiter allows, if necessary, to open the sash like a window. However, nothing prevents you from installing a comb on windows with a tilt-and-turn mechanism. Its use will reduce the gap formed when the sash opens in the vertical direction.

The design consists of a strip with slots and a window sash position lock (rod). The strip is mounted to the frame, the clamp is installed in the window sash. By installing the latch in one or another groove, it is possible to open the window within 1-10 cm. The opening angle depends on the length of the strip with grooves and the number of them.

The more grooves the strip has, the more precise adjustment of the sash position can be achieved. The standard plank is 10-12 cm in size with 4 grooves.

Manufacturers of limiters usually indicate 2 main functions of the comb:

ventilation premises (especially relevant for windows that do not have supply valves, sashes that open exclusively horizontally);
protection double-glazed windows from damage due to sudden slamming of the sash due to a draft or strong wind.

Ensuring the safety of children and pets is another advantage of the limiter.

By adjusting the position of the comb, the user has the opportunity to open the sash wider or narrower. Thanks to this, it is possible to achieve an optimal microclimate in the room, preventing the formation of condensation on plastic double glazing without overcooling the room.

You can leave the window in this position even for the whole day (which is especially important in the warm season). By opening the window literally 5-15 cm and using a limiter, you will ensure optimal air circulation in the room. However, it is important to understand that the comb only fixes the window, but in no case is a locking device. Residents of the first floors should not leave their windows open and secured with limiters when leaving the house.

In addition to the obvious advantages, the design also has disadvantages, which are best learned about before purchasing and installing the comb. Installation of the device requires the presence of additional perforations in the profile, which slightly reduces the thermal insulation properties of the glass unit. The sound insulation coefficient is also reduced by 2-3 dB. Finally, the presence of holes leads to a decrease in the strength of the profile and possible violations of the geometry.

If we compare supply valves with limiters, then the latter, of course, are inferior to them in terms of safety and functionality. The operation of double-glazed windows with valves is more convenient, but such products are more expensive.

Species

The limiting elements may differ in the number of grooves. Standard models have 4 grooves, but there are also options with 5 grooves. In addition, there are several types of combs.

Outdoor

Designed for folding window sashes (for example, vents). It has 3-4 grooves, fixes the sash while ventilating the room.

Built-in

Invisible to the eye analogue of the external comb. In terms of its functioning and number of grooves, this option is identical to the one described above. The difference is the greater aesthetics of the window, since the built-in limiter is invisible.

Constant brake

Perhaps such a name will seem unknown to many, although, perhaps, everyone has come across such mechanisms for sashes. A permanent brake is usually installed on the doors of shops and offices. All a person needs to do is pull the door towards him and open it. No need to close. Thanks to the built-in mechanism, the door will close smoothly automatically.

A similar system is mounted on a window, preventing the sash from spontaneously closing or swinging open excessively. Such a mechanism should not be pulled by force when trying to cover the window, as it may break.

Cable limiter

Structurally, it consists of 2 elements, one of which is fixed on the frame, and the second on the profile. They are connected to each other by a metal-based cable (sometimes in a plastic braid). There are models where the cable is replaced with a thin chain. The micro-ventilation function is realized thanks to the short (up to 20 cm) length of the cable.

Unlike a standard comb, it does not allow you to fix the sash, but only holds it, preventing further opening of the window. At the same time, the cable stop is stronger than the comb and can withstand a breaking force of up to 550 kg (depending on the model).

For protection against children and unauthorized entry from the outside, a cable stopper is more suitable than a comb. For ventilation it is better to choose the latter.

When installed on swing sashes, the limiter can be mounted anywhere in the profile and frame; when mounted on tilt-and-turn structures, only in the upper part.

Handle-lock

This is the most effective limiter that provides protection against children opening the window. It is a metal handle with shut-off valves. There is a lock on its outer part. Opening is done with a key.

Using the key, you can securely close the sash or give it a folding position. In appearance, such designs are indistinguishable from ordinary handles. The inconvenience is the need to keep the key safe. To do this, find a place inaccessible to children. The use of a key is also provided for by the invoice and mortise locks, as well as a wrap-stop and blockers for sliding windows.

Depending on the material used, there are also several types of combs.

Plastic

This is the most accessible type. It comes in several color finishes and goes well with PVC structures. The base is ABS (impact-resistant) plastic. The standard number of grooves is 3-4.

The disadvantages include the lowest strength indicator and, accordingly, a shorter service life. It is not recommended to install such products on windows facing the windy side, since under heavy loads they can become deformed and burst.

Metal

Metal combs are stronger and more durable, and therefore have a higher cost. It is important to note that the metal of the product must have anti-corrosion protection. The best material for making the structure is considered to be brass. To protect it from corrosion, a zinc layer is required. Typically such products have 4-5 teeth. The color range is very wide (copper, gold, silver, gray shades).

Combined

Such a device includes 2 materials at once - plastic and metal. As a rule, the latter serves as the basis for the retainer, while the comb is made of plastic. The number of teeth can vary from 3 to 5. White products of this type are most often produced. Sometimes you can find brown combs designed for windows with a wood profile. Colored options are usually made to order.

Depending on the type of installation, there are limiters mounted under the sash handle, as well as analogues installed at the end of the window sash.

How to choose?

You can purchase products in specialized stores, departments household supplies, as well as from specialists involved in the production and installation of windows. It is better to give preference to designs made of durable materials simple shapes. This will increase the durability of the limiter and reduce the risk of its individual elements breaking off.

It is important that the limiter matches the design features of the double-glazed window and operating conditions.

For example, it is better to install activated brake mechanisms on balcony doors. For large windows, as well as attic double-glazed windows that open upward, you should choose only high-strength metal stops.

If you plan to actively use the double-glazed window and frequently open/close it, it is better to give preference to a mechanism with a lock and key rather than a conventional comb. Then the device will last longer.

The cost of products ranges from 100-500 rubles. It depends on the material of manufacture, manufacturer, number of grooves. The most affordable are plastic models, the more expensive are metal and combined. Also usually combs with a large number grooves have a higher price.

How to install?

Installing the comb will take literally 5 minutes. The process does not require professional skills; all the work can be done with your own hands. You will need the following tools and materials:

directly the window stop, the kit of which includes the comb itself, the clamp and brackets;
self-tapping screws, which are usually also included in the kit (you can select them yourself, the main thing is not to take fasteners whose length is more than 12 mm, otherwise it will damage the profile);
screwdriver or screwdriver;
a knife (construction knife or regular kitchen knife), with which you will need to pick up the plug;
pencil or washable marker for marking;
drill.

You can install a limiter in several stages.

After preparing everything you need for work, drill several holes in the window using a drill. With this tool you will get perforations without damaging the plastic of the profile. If you neglect this stage and try to screw in the screws right away, you will not be able to avoid cracking of the profile material.
Turn the plug at a right angle. To do this, find a special groove on its surface, pick it up with a knife and turn it 90 degrees. Once the procedure is completed, 2 bolts will be found under the plug. They need to be unscrewed.
Remember what position the window handle is in, then remove it. To avoid confusion, giving the handle the same position as when the window is open will help, that is, the handle should be perpendicular to the vertical of the window.

Place the stop bracket in the profile space so that it will later be under the window handle. Perforations for screws should be visible in the holes of the bracket. After this, the handle is installed on the bracket, that is, it returns to its original place.
Take the latch and align it with the axis of the bracket (it should fit into the grooves correctly). Having determined the optimal position of the latch, you should make the appropriate marks on the profile.
In the marked places, use a drill with a thin gimlet to make 2 holes. Then you can attach the limiter using self-tapping screws. After this, the installation is considered complete.

The installation of the latch at the end of the sash is carried out somewhat differently. This type of installation allows the comb to be located anywhere in the fixed part of the frame. To attach the latch, you should use a long self-tapping screw so that it can pierce both internal jumpers of the end part of the sash (it is also called overlay). Only in this case can you count on the reliability of the fastening. As with the previous method, it is important to pre-drill holes for the screws and then screw the fasteners into them.

Installing a stopper in the end part of the sash is usually an alternative option. They resort to it if there is fittings under the window handle or opposite it, due to which it is impossible to secure the latch.

It is important to note that the window stop installed in the sash overlap can only be used for plastic windows. Its use in a wooden profile threatens to crack the wood in the direction of its grain.

With this installation method, the risks of breaking the tightness of the double-glazed window and deforming the frame are minimized.

Manufacturers

Among manufacturers of window limiters, the products enjoy the trust of buyers Penkid. These are steel cable restraints, the strength characteristics of which are admirable - they can withstand pressure up to 550 kg. They cannot be broken, cut with a knife or cut with pliers. The cable length is 200 mm.
Roto limiters demonstrate unsurpassed German quality. The manufacturer gives a 10-year warranty for some of them. Plastic limiters for this trademark They are completely safe from an environmental point of view, and metal ones have multi-layer protection against corrosion.
Fittings from another German brand are characterized by high reliability. Reha u.

Plastic double-glazed windows operate in two modes: slot micro-ventilation and full opening of the sash. However, such provisions are often insufficient. A practical and affordable solution to the problem is a window opening limiter. The device holds the sash at a given level, preventing it from slamming shut or swinging open in the event of a draft. Let's figure out what types of window latches exist and how they work. Let us outline the selection rules and technology for installing the limiter.

A window restrictor controls the flow of air into the room and holds the sash in the selected position. The bar sets a fixed opening gap in the range of 1-10 cm.

Sash blocker

Tasks of the window sash stop:

Air supply adjustment. The required ventilation intensity is set in the room - the air flow circulates in a certain volume through a fixed slot.
Safety. The bar blocks the position of the window - it will not allow it to open wider than the specified level. This is very important for families with small children and pets.
Preventing drafts. The mechanism keeps the sash from suddenly swinging open. Thanks to this, the likelihood of unexpected drafts is reduced. In addition, there is no risk that nearby objects, flowerpots and expensive double-glazed windows will be damaged by abruptly opening the window.

FYI. Poor room ventilation is one of the main reasons, and in rooms.

Components of the limiter

A typical blocker is called a “comb” or “crocodile” because appearance devices. The latch has a simple design and operation scheme.

The simplest model window limiter consists of two parts:

Comb. An extended bar with grooves and a hinged connection for raising/lowering the mechanism. The number of “notches” on the plate determines the opening range of the window. The most popular are four-position models.
Latch. The response part is located on the movable sash. A small metal pin holds the comb in position.

Window stop device

The use of a limiter involves selecting the window opening level and placing a pin between different positions of the comb.

Pros and cons of using a blocker

The main advantages of limiters for plastic windows are ease of use and the safety of operation of the sashes. Additional advantages include:

affordable price;
Possibility of application on previously installed windows;
ease of installation - all work can be done by yourself without the involvement of specialists or the use of expensive equipment;
simple care of the mechanism and the ability to self-replacement in case of breakdown.

Locker on the window frame

However, this method of fixing a window sash also has disadvantages:

non-compliance with installation technology is fraught with damage to the frame and deterioration of tightness parameters;
fragility of the structure - active, careless operation can damage the latch or lead to the strip breaking;
in the cold season, the use of a limiter is not relevant - the air inside the room quickly cools. One way to ensure ventilation in winter is to install.

A simple comb is not enough to fully protect children. To ensure complete security, lock models must be installed.

Types of window sash clamps

Window stops for PVC windows differ in the material of manufacture, installation location and mechanism of action. The listed parameters determine the strength of the bollard, its durability and reliability in terms of security.

According to the material of manufacture

For installation on PVC windows, three types of models are used:

plastic;
metal;
combined.

Plastic. An affordable device that is perfectly compatible with PVC profiles. Limiters are produced in several colors, the standard number of positions is 3-4 positions.

Plastic limiter

Disadvantages of PVC blockers: low strength, short term services. It is not advisable to install such modifications on sashes facing the windy side - heavy loads can cause deformation of the plastic.

Metal. More durable and therefore wear-resistant blockers. The most preferred are brass stops with an anti-corrosion zinc layer. The color range of metal retainers is limited: golden, silver, grayish and copper shades. The downside is the high cost.

Metal limiter

Metal-plastic. Combination devices include: plastic comb and metal retainer. As a rule, the bar white. Interesting multi-colored options - to order.

Combined type of blocker

By mounting method

There are 2 installation methods:

installation under the handle;
installation in the overlap of the sash.

The first option is conventional combs mounted on a fixed part of the frame. The bar rises or falls without taking up extra space or clinging to the curtains.

Placement of the limiter under the handle

The second option involves installation at the end of the sash. The pin is fixed with long self-tapping screws that pass through both sash overlap bridges. This type of fastening is more reliable.

The window sash opening limiter is suitable only for plastic structures. Installation on wooden frame can lead to its deformation along the fibers natural material due to significant forces occurring on the pin.

Blocker at the end of the sash

By mechanism of action

Limiters for opening plastic windows design features and operating principle can be classified into the following groups:

External comb. A primitive “crocodile” for flaps. The model fixes the window for ventilation, but the degree of protection for children is insufficient.
Built-in limiter. An analogue of the external comb, the functionality corresponds to the previous device. Plus - aesthetics, hidden placement. The downside is that it does not provide security.
Constant brake. Blocks spontaneous opening and excessive swinging of the sash. A similar mechanism is used on the doors of offices and shops. Disadvantages: high cost, risk of breakage if the window is opened suddenly.
Handle-lock. Effective protection against children's access to windows. Externally it is an ordinary handle, but inside it is built shut-off valves. The downside is the limited choice of sash position and the need to keep the key safe.
Window limiter with cable. The capabilities are similar to a comb, but can withstand a tensile force of up to 550 kg. Installation on swing sashes is permissible anywhere; on tilt-and-turn frames – at the top of the structure.

Cable window rotation limiter

How to choose a window comb

Before purchasing a window stop, study the characteristics of different modifications. When choosing, experts recommend adhering to the following rules:

It is better to install activated brake mechanisms on balcony blocks.
For attic double-glazed windows and large windows, it is necessary to select metal fasteners of increased strength.
For active use and frequent opening/closing of the sashes, it is advisable to choose a window limiter with a cable. Alternative option– blocker with a locking mechanism.
If there are often drafts in the apartment or the windows are located on opposite sides, refuse plastic products.
To protect children as much as possible, it is necessary to install special restrictions for safe ventilation or.

How to install a limiter on a window

The technology for installing a comb-type window retainer can be divided into three stages. First - preparatory activities. The second and third are the installation of the clamp and the bar with grooves, respectively. Let's look at each of them.

Preparing tools

Prepare your tools in advance. Having everything you need nearby will help you stay focused on your work.

Required tools and materials:

limiter with pin;
screwdriver or Phillips screwdriver for fixing elements;
self-tapping screws up to 10-12 mm long – larger fasteners can damage the window profile;
construction or household knife - necessary for prying off the plug;
pencil for marking - it is better not to use a marker on white plastic so that there are no marks left;
drill and drill bits.

You should have a tape measure and instructions on hand, supplied complete with the limiter for PVC windows.

Required Tools

Installing the retainer

The primary task is to install the pin on the opening window sash.

Sequence of actions:

Pry off the plug on the handle and turn it 90° - access to the fasteners will open.
Fix the window in open mode and remember the position of the handle - perpendicular to the vertical of the sash.
Unscrew the upper and lower bolts and remove the handle.
Place the comb bracket so that the board is under the window handle. The pin should point towards the return door.
As a rule, the holes in the bracket coincide with the holes where the screws are located.
Attach the bar with the pin, reinstall the handle and tighten the bolts.
Return the handle plug to its original position.

Installation of the window stopper

Bracket Attachment

This is the most critical stage of installing a limiter on a window. Here it is important not to make a mistake with marking and preparing the holes for mounting the comb - it will not be easy to correct the defect. Illiterate actions can lead to depressurization of the glass unit.

Work technology:

Close the sash with the lock and mark the level of the bracket. The pin should be located opposite the comb, but not interfere with the free opening/closing of the window.
Mark the planned location with a pencil.
Holding the toothed strip in the designated area, try to fix the window and check the operation of the sash.
If the elements are well joined, the limiter does not interfere with the use of the double-glazed window, then you can finally screw the bracket to the frame with self-tapping screws.

Checking the operation of the sash opening blocker

It is not advisable to “set” the guide on glue. Constant loads will quickly damage the strength of the coupling and the bar will fall off.

The entire process is clearly demonstrated in step-by-step video instructions:

Features of replacing an old element

Before installing a new limiter on plastic windows, you should consider several important points:

We need to find an analogue of the old comb. When purchasing, pay attention to the basic dimensions: the diameter of the pin and the distance between the mounting holes.
Even if only one element fails, the entire system must be replaced. Fasteners different models may have dimensions that will not fit the new grooves of the strip.
To change the brackets you need to unscrew two screws.

Replacing the sash opening limiter

When rearranging the bar, a number of rules are followed:

Remains of plastic on the screws must be removed - if this is not done, there is a risk of breaking the thread during tightening;
it is advisable to get into the old, used thread - first turn the self-tapping screw counterclockwise, and as soon as the fastener “falls off”, change the force vector.

If the holes of the new comb do not correspond to the old ones by 1.5-3 mm, they can be bored out with a file, and the bar itself can be secured with self-tapping screws with wide heads and press washers.

Making a limiter with your own hands

For the windows of a country house you can build homemade device to regulate ventilation. You will need some simple materials:

a piece of wire with a diameter of 2-3 mm;
2 small nails - will act as a pin;
2 large nails - for making brackets and then fixing the limiting device on them.

Making a window blocker

Assembly algorithm:

Bend the wire in half, forming a loop in the middle and small curls along the edges.
Make an arch using long nails. Use pliers to give them the desired shape.
Drive staples from long nails into the fixed frame of the sash at a height convenient for adjustment.
Thread one end of the wire into the bracket.
Attach a small nail - a tripod - to the movable door.
To adjust and fix the position, the wire ring must be put on the clamp.

If the invention provides several turns of wire, this will expand the number of window opening modes.

A homemade device does not require financial investments, but in terms of strength it is noticeably inferior to purchased analogues.

Popular manufacturers of window clamps

The quality of the limiters is largely determined by the manufacturer. The following brands have earned a positive reputation among users:

Penkid. A Turkish company specializing in the production of steel window opening limiters with a cable. Metal models can withstand a load of 550 kg, cable length is 200 mm. The blocker cannot be broken or cut with a knife.

Previously, to fix the door, various objects or crumpled paper were placed under it. However, progress moves rapidly, and today no one uses sheets of paper to hold the door. And along with such door fittings as handles, latches and hinges, as an alternative to the well-known door chain, special door opening limiters are widely used, which allow the door to open slightly at a given distance.

The need to limit door opening

Limiting door opening using special latches can be useful in different cases, most often - when it is necessary to rationally plan the space in the room and ensure the safety of opening the door. In this way you can protect not only door leaf, but also furniture and walls from damage caused by excessively swinging the door open, as well as prevent injuries that can be caused by a sharply slammed door from a draft.

Sometimes it becomes necessary to fix the door in a certain position, for example, if you need to bring a large object into the room or ensure the unhindered movement of large groups of visitors. This is often necessary when the house has small child, who may accidentally pinch his fingers or hit the doors. It is also somewhat burglar-proof.

The use of special clamps where they are installed at the entrance is becoming especially relevant. double doors, which are not easy to hold open at the same time. For example, in suburban buildings it is often customary to install two entrance structures - steel and glass. The first door can be fully open during the day, held by a latch in a given position, and the glass sheet is used at this time as the main protection and additional source lighting.

Types of door opening limiters

Door opening limiters are presented in a wide range of door fittings market. Each manufacturer strives to make them in intricate designs, polished, chrome-plated, silver or gold, as can be seen in the photo of the door limiter.

Floor limiters

There are different types of stoppers that are installed on the floor. Some of them are capable of holding the door leaf in a given position, others simply do not allow it to swing open enough to damage the standing pieces of furniture behind the wall or the wall decoration. Among them there are mobile and stationary products.

Stationary floor models include:

Magnetic holder. The principle of its operation is quite simple: a small metal plate is screwed onto the door leaf at the bottom, and the stopper itself with a magnet is attached to the floor in the place beyond which the door should not swing open. When the door is opened, such a plate is magnetized to the stopper and fixed in this position.
Door stop. This is the simplest product that does not fix the door itself, but at the same time does not allow it to open more than necessary.

Mobile floor clamps are much more diverse:

The most common door stopper in the open position is a regular wedge that has a non-slip base and can be made in the form of a figurine toy.
Another type of floor stopper is a device that fits onto the bottom end of the door, and its legs, which are non-slip, rest against the floor on both sides.

To close or open the door, just press the floor limiter of the interior door with your foot, thereby releasing it from the groove. There are other configurations of similar devices on sale, but they all work on a similar principle.

Wall stops

According to their purpose, wall clamps are divided into door slamming and door swinging limiters. Door swing limiters are small parts various forms and styles that are attached to the wall with screws and do not allow the door to hit it. Such devices are simple and magnetic. Their installation is justified in the case when you do not want to spoil expensive parquet with floor limiters, or if under your floor covering There is a "warm floor" system.

The open door stoppers that are attached to the top trim are considered more functional. The design in the tilted position does not prevent the door from closing, but if you turn it down 90 degrees, it will create an obstacle to the door closing completely. However, we want to reassure you: you should not be afraid that wall or floor opening limiters will damage the finish of the door. They are made from soft materials or equipped with a rubber lining at the points of contact with the door leaf.

Door stops

If you need to hold the door leaf at the desired angle, then you should pay attention to the door opening angle limiter, which consists of a metal body that is screwed to the door, as well as a brake pad. In order for the brake pad to extend and the door to lock against opening, you just need to press the foot pedal. To remove the fixation, simply lift the brake pad by pressing the lever.

Locking device limiters

When you need to restrict access to specific room, as a rule, locking device clamps are installed. Locks are rarely installed on interior doors. If it is possible to restrict access to the room, for example, to the bathroom, then it is customary to choose door handles with stopper. Such handles are equipped with a latch that holds the door in the closed position using a tongue that fits into the hole of a special strike plate on the frame. Magnetic latches are no less popular.

For entrance doors, locks are installed so that it is not possible to open the door with a key from the outside. Entrance doors often tend to slam shut at the most inopportune moment, for example, when you decide to take out the trash. Magnetic opening limiter front door This will not allow this to happen, since it holds the lock tongue inside the mechanism. For an interior door, a similar function is performed by closing limiters - attachments on the door or stand-pegs under the bottom of the door.

Door stop material

There are a huge number of door locks on store shelves. The price of door opening limiters often depends on the material from which the device is made. Steel, aluminum, steel alloys, brass, plastic and wood can be used to produce door stops. The stronger the raw material from which the latch mechanism is made, the more it can withstand a greater load.

If the latches are intended for a massive and heavy door to the living room or bedroom, it is worth buying stable mechanisms made of metal. If you want to make your bathroom door functional, just choose plastic limiter, which conditionally makes it clear to guests or household members that the room is occupied. If you want to protect your children from accidental bruises on their fingers, then you need to buy plastic or rubber door stops.

If you plan to prevent your front door from swinging open, you should opt for metal latches. In addition, they must have strong magnetization, which can stop the movement of the massive door leaf. For lightweight interior doors, magnetic fasteners with a lower magnetizing force are intended.

If you have to protect furniture sets and finishing from the strong swinging of the door, it is better to choose wall clamps that stop the door from the wall at a certain distance. To prevent damage to the door finish, you should choose stops made of soft materials, for example, rubber, or clamps with soft pads.
