Lock Features

Lockmaster locks can feature normal hooks or hooks with an anti-lift pin. Hooks throw upwards, with hook cases measuring 136mm high. Deadbolts have a chamfered edge and cases measuring 154mm high.

Measuring Guidelines

Backset Measurement: To measure the backset, take a tape measure and measure the distance from the edge of the door to the center of the lock cylinder. This distance is crucial for ensuring the lock fits properly in the door.

Centres Measurement: To measure the centres (PZ), measure the distance from the center of the keyhole to the center of the handle hole. This measurement is essential for aligning the lock correctly with the door handles.

Faceplate Measurement: To measure the faceplate, remove the existing lock and measure the width and height of the faceplate. This ensures that the new lock will fit seamlessly into the existing cutout.

Operation Selection: When selecting the operation from the drop-down, consider how you intend to use the lock. Options may include lift lever, double spindle nightlatch, or other configurations based on your security needs.
