From the moment a child begins to crawl the explorer within is brought to life ready for the many adventures ahead. At an early age these adventures will often involve satisfying their curiosities of all the interesting things around them and discovering how to do things and how different things work. As safety is not always on the mind of a fearless adventurer, it can be very easy for a child to get into a dangerous or even a life threatening situation. You do all you can to babyproof your home, however, there often lies a forgotten risk – an easily opened or ajar window.


The Royal Society for the Prevention of Accidents (ROSPA) reports that, each year in the UK, 4,000 children under the age of 15 are injured through falling from windows, 2,000 of these children being aged between 0-5 years old. It is impossible to watch a child every second of the day and, even if you do keep a close eye on them when they are near windows, you cannot guarantee that family members, friends or babysitters will do the same. It is imperative that anyone who looks after your children is made aware of how easy it is for children to be hurt or even killed from falling out of a window.
Luckily, there is a very simple, affordable and effective solution to this problem – the MAX6MUM SECURITY window restrictor. The window restrictor limits the opening of a window to no more than 100mm - enough to enable air to circulate throughout your home, but not enough for your child to fit through. The opening width can be decreased if necessary during installation by positioning the fixing points further apart from each other.
The MAX6MUM SECURITY window restrictor can be fitted to any profile and style of window, and even doors – including aluminium, wood, metal and uPVC profiles. It is extremely easy to install yourself, and comes with all the parts necessary to do so, including self-drilling screws. A step-by-step guide of how to fit the window restrictor is also provided, meaning you can easily fit the restrictor in just a couple of minutes.
The window restrictor cable is locked into place with a key so that, should it be required, the window or door can be fully opened. This is simply done with a half-turn of the key. As the restrictor can be unlocked, it can also be used on fire escape windows, providing that the key is kept within easy reach of the window.


Some window restrictors in the industry claim that the cable can withstand forces over 500kg. However, despite this, do not be fooled into thinking that this will help keep your child safe. Although the cable can take great weights, it does not mean anything as it is the strength of the locking system which the cable locks into which stops the window from opening. The MAX6MUM SECURITY window restrictor can withstand over 100kg of force once the cable is locked into the locking system, making it one of the strongest window restrictors available (the industry standard is around 50kg of force). This means that you can relax in the knowledge that, even if your child gets themself into a situation where they could fall out of a window, the window restrictor will keep your child safely inside the home.
Another unique feature of the MAX6MUM SECURITY white and brown window restrictor is that the plastic used on both the cable and locking system is MRSA resistant. A special chemical has been added to the plastic, which kills the MRSA virus when touched. The window restrictor therefore not only stops your children from falling out of a window, but also helps prevent your child – and yourself – from catching the MRSA virus.
In addition to being a child window safety device, the MAX6MUM SECURITY window restrictor also prevents burglars from using the window as an access point to the home, especially if the window is on the ground floor. As the restrictor cable is made from hardened steel, it is extremely difficult to cut. This means that, during the summer, you can leave your bottom windows open to let fresh air in, and feel secure knowing that someone is not going to easily open the window and break into your home.

                     how tot fit a 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 remove the plastic cap. To remove the cap, hold both sides of the plastic cap, and press down on where the key goes in (C1). This will make the locking system pop out.

3. Place the locking system on the window frame (1A) (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.

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

5. Take the steel cable (B) and place the knuckle end (shaped like a T) into the locking system already fixed to the window. Place the other end on the fixed window panel (2B) (making sure that the cable is not tight and has length for the window to open around 10cm – see diagrams 1 and 2), and pull the plastic cap away from the end of the cable (a bit of plastic preventing the cap from locking will fall out, throw this in the bin).

6. Mark the 2 screw holes on the end of the cable using a pencil.

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

8. 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.

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

10. 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.

How to Use

At all times is it recommended that you keep the window restrictor locked to prevent children accidentally opening the window and falling out. The restrictor is designed so that it allows ventilation into a room without having the window fully wide open, which can be very dangerous. If you do require the window to open fully wide, use the key to unlock the restrictor, and remove the knuckle from the locking system. This will allow the window to operate normally. Remember to lock the restrictor afterwards, by placing the knuckle back into the locking system and locking it with the key.
