Window Safety Restrictors - FAQ's
Will your range of window safety restrictors fit all windows?
Not all of them. The casement windows (normal outward opening windows) must have friction hinges like the ones found typically on uPVC double glazed windows. These window safety restrictors are generally, but not always, fitted inline with the hinges on both sides of the window. The gap is therefore correct for these devices to work correctly, although we do provide a few purpose made packers to help if there is some adjustment needed. If you have timber windows then use cable window restrictors as these can be fitted straight onto the window.
Are window restrictors handed?
Some of them are and you will be prompted when ordering to select the correct one. This diagram will help you:

How easy is it to fit window safety restrictors?
As long as you have a PVC or aluminium type window (timber with friction hinges too) then the concealed window restrictors are relatively easy to fit, if you follow the instructions given. If you are fitting above ground floor then it is much harder as the pins need to be fitted to the opener and this can only be done from the outside. Some fitters bring the window inside the room by removing the opener from the hinges, but great care must be exercised if you do this and two people are a must. Cable restrictors do not require any form of fitting from the outside and are the easiest to fit.
Do the safety restrictors provide security to an open window?
They will slow down any intrusion but they must not be classified as secure. Window restrictors are designed to limit the amount of opening, to avoid people accidentally falling from windows above ground level. An open window can never be treated as secure, although it will obviously slow down any attack.
Are any of these window safety restrictors child-safe?
There are several options available that make it more awkward for children to manipulate the restrictor device. The R02 is designed for a two-hand/two finger operation, the R03 is a fixed restrictor (no release) and the R04 is key-locking. The restrictor should be positioned on the window to ensure the air gap is no greater than 100mm (10cm), the size of a child’s head.
Why do you recommend two safety restrictors on a top hung window (window hinged from the top)?
If someone should accidentally fall against a window the unrestricted side may be forced wider on its hinges at that side and open the gap of the window further. This is particularly the case with larger windows whereas the smaller fanlights are ok with one subject to your own risk-assessment. One restrictor each side will provide a sturdy brace and also avoid over-stressing the hinge on the unrestricted side.
Where should I fit a window restrictor?
Restrictors should be fitted to any window you consider is a safety risk. This may be a children’s room or particularly large windows above ground level. However, consider the points below ‘What do I need to know’.
What do I need to know about window safety restrictors?
Some key points to be aware of:
- Ensure that the window is not used as a fire-escape.
- Ensure that all adult occupants are aware of the device and understand how to release the restrictor.
- Any keys supplied with a restrictor should be kept in a safe and identifiable place for all adult occupants.
- If using the R03 restrictor please note that this device is non-releasable and requires the removal of fixing screws to open the window fully.
- All restrictors should be fitted to windows to create an opening air gap no greater than 100mm(10 centimetres) for child safety.
- Restrictors do not improve the security of your window.
- Two restrictors should be placed on top hung windows either side of the opening window (LH and RH).
How easy are these safety restrictors to fit?
You will need to mark out and drill fixing holes carefully in the correct position for the device to operate. A full installation sheet is provided with each restrictor.
Do the restrictors hold the window in a fixed stay position?
Only the R03 is capable of doing this via two screws on the friction slide pad.
