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

The restrictor is not key operated, instead the push and turn bullet provided allows the window to be fully opened if required, while preventing fall and providing home security when locked. The restrictor can fit most window sizes and types, including uPVC, timber and aluminium.

The Pro-Twist by Jackloc is incredibly strong, with a reinforced 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.
