Product Details

Lockmaster Multipoint Lock Case – 45/92 (LM459262DB-LC)

This Lockmaster genuine gearbox is designed as a replacement for the active lock case on multipoint door systems. It features a 45mm backset with dual PZ measurements of 92mm and 62mm, accommodating various handle configurations.

The lock case includes both a spring latch and deadbolt mechanism. An 8mm double spindle design provides compatibility with sprung handle sets. Note that this is an unsprung gearbox, so your handle set must include a spring cassette to prevent handle droop.

This lock case is fully reversible without requiring a handed version. To reverse the latch, simply undo the screw in the latch, remove it, reverse the orientation, reinsert, and replace the screw.
