Ventlocks - Locking

Patented worldwide and intuitive in its use the Locking Ventlock™ is designed to allow a sash to be left open a few inches for ventilation without compromising security. 
Fitting is simple and causes very little stress on the sash. Just screw the whole unit into a 14mm diameter hole.

The special key which is supplied as part of the Ventlock™ system releases an inner barrel which prevents the window from being moved. The barrel revolves freely preventing it from being cut.
Comes complete with matching Mini Strike Plates.
