About the Pro-Twist by Jackloc Cable Window Restrictor

The Jackloc Pro-Twist Window Restrictor is an incredibly strong keyless cable window restrictor, with a push and turn lock and release mechanism.

This restrictor is not key operated, instead  the push and turn bullet design allows the window to be fully opened if required, while preventing falls and providing home security when locked.

The Pro-Twist Keyless Window Restrictor can fit most window sizes and types, including uPVC, Timber and Aluminium.

The Pro-Twist by Jackloc is incredibly strong, with a high tensile stainless steel cable, security screws and heavy-weight body. Each product is individually tested in the manufacturing process to hold a force of 3,600 newtons or the equivalent of 34 stone.

This window restrictor comes with four security screws to help keep homes safe and is also available in a range of special order colours and finishes. Easy to fit – take a look at our window restrictor fitting instructions
