How To Measure My UPVC Gear Box / Multi-Point Door Lock?
When trying to identify or measure any multi-point lock, there are two critical dimensions required - the PZ and the Backset. The centre case height and depth are also useful.
A. The PZ dimension - measured from the centre of the spindle (follower) hole to the centre of the top diameter of the lock cylinder (barrel) hole. (If there are 2 spindles always measure from the top spindle hole).
B. The Backset dimension - measured from the front of the lock faceplate to the centre of the spindle (follower) hole.
C. Case Height - the height of the centre case.
D. Case Depth - the depth of the centre case.
