Description
This Lockmaster/Mila Master 2 Hook 2 Roller multipoint lock is a complete strip that secures your door with two forged steel hook bolts, two anti‑lift pins and two compression rollers. It also features a deadbolt and latch in the centre case plus top and bottom shoot bolts, giving smooth multi‑point locking along the full length of the door. The 35 mm backset and 92 mm centres make it a direct replacement for standard uPVC or composite door mechanisms. A reversible two‑spindle design means it works with single or split spindle handles. With a 1040 mm distance between the hook bolts and a slim 16 mm faceplate, this one‑piece mechanism is suitable for timber, uPVC and composite doors.

How do I Identify my uPVC Door Lock
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.
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
Measure the Backset (Measurement A)
The backset is the distance from the front edge of the faceplate to the centre of the keyhole (cylinder).
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).
