WILKA 1438 Mortise Lock Stainless Steel 92/35 High Durability 200,000 Cycles

Product Overview

The WILKA 1438 92/35 mortise lock is designed for use in both exterior and interior doors?including high-weight doors exceeding 200 kg?in public buildings and commercial environments. Its universal configuration supports left- or right-hand operation and the lockcase is constructed with a stainless steel faceplate, with the latch and deadbolt made from nickel-plated zinc alloy for increased corrosion resistance and durability.

What distinguishes this lock is its endurance rating: tested for 200,000 operating cycles under a 25N latch load. This level of tested longevity addresses procurement concerns around frequent maintenance or premature failure, making it a solid choice for those specifying hardware for high-traffic, high-use facilities such as educational campuses, hospitals, or municipal buildings.
