Corbin Russwin ML2055LL626 Classroom Mortise Lock

Product Description

The CORBIN RUSSWIN ML2055LL626 is a single cylinder classroom mortise lock designed for commercial and institutional door applications. The lever-by-lever configuration provides a consistent, ergonomic operation on both sides of the door. The lock body ships complete with a strike, front plate, and mounting screws, making it a ready-to-install assembly for qualified locksmiths and commercial door hardware technicians. Finished in satin chrome (626), the unit is suited for high-traffic corridors, classrooms, and institutional spaces where durability and security are required.

This mortise lock is built for commercial and institutional settings such as schools, universities, healthcare facilities, and government buildings. The classroom function is a common specification in K-12 and higher education environments, where the lock must allow free egress from the inside while permitting keyed entry from the outside. The lever-by-lever design meets typical ADA lever handle requirements for accessible hardware installations.
