Mortise Frame Lock 92ZR

92mm Roller Latch Narrow Mortise Lock

The Williams 92ZR is a 92mm roller latch narrow mortise lock designed for frame doors where quiet operation is required. It shares the same slim body, 92mm centre distance, and 30/35mm backset options as the standard 92ZR, but replaces the latch with a roller mechanism that reduces metal friction noise during closing. Manufactured to EN 12209 and DIN 18251, the 92ZR accepts euro profile cylinder. It is the recommended choice for noisesensitive environments such as hotels and hospitals, balancing durability and user comfort.

Features
