WILKA 038R Additional Mortise Lock Stainless Steel 30mm for Heavy Doors 200,000 Cycles

Product Overview

The WILKA (038R) 30 mm additional mortise lock is intended for installation in both exterior and interior doors, including those with a leaf weight exceeding 200 kg. Commonly specified in public utility buildings, it features a robust stainless steel faceplate and a nickel-plated ZnAl bolt, providing enhanced durability for high-traffic and heavy-duty environments. The lock is rated for 200,000 operating cycles under a latch load of 25N, indicating its suitability for intensive use applications.

Distinct from standard mortise locks, the 038R model's certified endurance of 200,000 cycles minimizes the risk of premature failure in frequently operated doors. This resilience is particularly valuable for facility managers and procurement specialists in public sector projects, where reliability and long-term maintenance cost reduction are procurement priorities. Ideal for bulk orders in commercial, educational, and institutional construction projects.
