DOM POLSKA 110/TW 72/50 WC Mortise Lock Left Narrow Case Class C White Zinc

Product Overview

The Zamek 110/TW 72/50 WC is a left-handed mortise lock designed for bathroom doors in public and commercial buildings, supporting door weights up to 100 kg. It features a latch and bolt mechanism, withstands up to 100,000 operating cycles at a 10N latch force, and has a narrow lock case compared to standard 72 mm backset mortise locks. High corrosion resistance is confirmed to Class C, making it reliable for high-traffic, demanding environments.

A distinguishing feature of this model is its compact lock case width, which facilitates installation in doors with limited space or slim profiles where standard cases do not fit. This reduces adaptation work during retrofit or renovation projects and decreases procurement risk for facility managers. Particularly suited for bulk specification in public sector buildings, offices, or institutional facilities requiring heavy-duty, space-saving locking solutions.
