The Royal Society for the Prevention of Accidents provides research that states that in the UK over 4,000 children under the age of 15 are injured yearly from unsecured windows which they fall out of, with 2,000 of these accidents involving children under 5 years old. A small yet very effective and extremely affordable solution is the UAP window restrictor. The window restrictor has a 20cm long cable, which when installed correctly will limit the opening of the window to under 100mm. Not only will this prevent children from being able to fit through the gap, but it also allows enough air to circulate around a room.

The black window restrictor is lockable, and can be unlocked using a key if necessary, and the window will then be able to be opened fully. Due to this reason, it is possible to fit the UAP lockable window restrictor on fire escape windows, provided that the user keeps the key within easy reach.

One of the important features on the UAP black window restrictor is the strength of the cable once locked into the locking system. Some window restrictors claim that the strength of the cable exceeds 500kg. However, even though this may be true, it does not mean anything as it is the strength of the cable once locked into the locking system that actually matters. The UAP window restrictor, once the cable in locked into the locking system, can withstand forces over 100kg, which is more than enough to take the weight of any child. This is twice the industry standard which is 50kg!

The cable itself is made from hardened steel, which makes it extremely difficult to cut. It makes the window restrictor ideal for customers who are based on ground floors, and want to leave their windows open but are afraid that they may be broken in to!

Technical Information

What Is Biomaster?

What makes the window restrictor even more unique is that it is Biomaster protected - protection again the dangers you can't see!

Biomaster ensures effective antibacterial protection for the effective lifetime of the product, helping to keep surfaces clean and hygienic, and reduces the threat of cross-contamination from harmful bacteria – such as MRSA, E.coli, Campylobacter and Listeria and even viruses like the common cold and influenza. Window restrictors, especially those found in commercial properties such as schools, hospitals and hotels, are often handled by many adults and children and can therefore facilitate the spread of harmful infections.

Fitting Instructions

Fitting Your Lockable Window Restrictor

1. You will first need to decide where on your window you want to put the restrictor. We suggest that you fit the window restrictor in the middle of the longest side opposite the hinges.

2. Take the locking system (C) and place it on the window frame (it does not matter if the key hole is at the top or bottom). Mark the 2 screw holes on the window frame using a pencil.

3. Using a drill or screwdriver, screw two self-drilling screws (A) into the locking system to secure it to the window.

4. Take the steel cable (B) and place the locking end (shaped like a T) into the locking system already fixed to the window. Place the other end on the window panel (making sure that the cable is not tight and has length for the window to open around 10cm) and mark the 2 screw holes using a pencil.

5. Using a drill or screwdriver, screw two self-drilling screws (A) into the end of the cable to secure it to the panel.

6. Once both parts are secure to the window, check to make sure the cable fits into the locking system. Take the key (D), place it into the locking system and make sure it locks and releases the cable.

7. Lock the cable into the locking system and open the window. This should allow the window to open approximately 10cm.

8. If everything works correctly, remove the cable from the locking system and attach the plastic cap by pressing it securely onto the locking system. On the end of the cable, attach the plastic cap.
