Jackloc cable window restrictors will enhance the security of any building and the safety of any persons within it. Once fitted, the window restrictors cannot be removed, further increasing the safety, security and reliability of the system.
If the window hinges at the top or bottom the lock needs to be placed a good distance from the hinge, to function as a safety device. Sounds confusing? Experiment a bit and think about the gap your child could squeeze through, before you fit.
