DOM POLSKA Zamek 110 Mortise Lock Narrow Case 72/55 Left White Zinc Class C

Product Overview

The Zamek 110 72/55 with a 20/235 mm faceplate is a mortise lock designed for left-hand doors in public utility buildings. With a corrosion resistance rating of Class C and the capability to withstand doors weighing up to 100 kg, it is suited for intensive commercial and institutional environments. The lock has passed durability testing for 100,000 operating cycles under a 10N latch load, demonstrating compliance with demanding usage standards.

A key differentiator is the narrower lock case (?węższa puszka?) compared to standard mortise locks with similar backset and spacing. This slimmer profile simplifies installation in doors with smaller cutouts or limited frame depth, reducing the need for structural door modification. Facility managers and fit-out contractors handling renovation or retrofit projects in public buildings, where door leaf thickness and space are constrained, will find this lock especially suitable.
