Centurion 45mm x 35mm White Patio Door/Window Lock

These window and patio locks are an easy to operate push button lock that is released by the use of a key. It works by being fixed at a right angle (90°) to the glass and is normally mounted at the bottom of the door or window. This simple but extremely effective device is solidly fixed with two screws and the lock bolt engages into the sliding leaf of the patio door, stopping anyone on the outside from forcing the door to slide open.
