How do I Identify my uPVC Door Lock
1
Check for a Manufacturer’s Name
Look along the faceplate (the long metal strip on the edge of the door). Many locks have the brand stamped into the metal.
2
Identify the Locking Points
Look up and down the faceplate to see what locking mechanisms are fitted in addition to the latch and deadbolt. Example Answer: 2 Hooks and 2 Rollers
3
Measure the Backset (Measurement A)
The backset is the distance from the front edge of the faceplate to the centre of the keyhole (cylinder).
4
Measure the PZ / Centres (Measurement B)
This is the distance from the centre of the keyhole to the centre of the square spindle hole (where the handle goes through).
