About the Perma by Jackloc Cable Window Restrictor
The Perma by Jackloc is an incredibly strong Window Security Cable. It provides security from intruders and safety from falls for both homes and commercial settings.
The Jackloc Perma keyless window restrictor doesn’t have a key to over-ride the opening restriction, instead it’s permanently fixed which prevents tampering and accidental release. The result is unrivalled window security while still allowing windows to be opened to allow in fresh air without the risk of falls and intruders.
This type of window security device is suitable for most windows. It can be fitted to uPVC, Timber and Aluminium frames. The strength in the Perma by Jackloc window restrictor comes from the reinforced cable and security screws. In testing, the product is proven to hold a force of 3,600 newtons, which is the equivalent of 58 stone.
The Perma by Jackloc keyless Cable Window Restrictor comes with grade four security screws to help keep homes safe and help to prevent burglary. It is available in white, black and brown colour options.
Jackloc window restrictors far exceed required standards and are designed, manufactured and tested in the UK.
