Door & Window Restrictors

A window restrictor is a safety device which prevents a window from opening more than a fixed distance and to prevent anybody from getting in and out the window. Perfect for childproofing your home or simply providing a little extra security and safety, our extensive range of window restrictors allow for limited opening of windows. Shop for window safety locks and cable window restrictors manufactured by leading brands such as Jackloc, for quality locks you can rely on.

The telescopic friction stay is used for limiting the opening angle of the door or window, designed for inward or outward opening applications. You can also find more window security here at Handle Hardware including casement stays and fasteners, sash stops, fanlight catches and more!
