Corbin Russwin ML2055LL630 Classroom Mortise Lock

Product Description

The CORBIN RUSSWIN ML2055LL630 is a single cylinder classroom mortise lock designed for commercial and institutional door applications. It ships as a complete assembly including the lock body, strike, front plate, and mounting screws. The lever-by-lever trim configuration allows entry from outside with a key while the inside lever remains free-turning, a standard requirement for classroom security functions. Finished in satin stainless steel (630), the unit resists corrosion and holds up to high-traffic conditions common in schools, healthcare facilities, and government buildings.

This mortise lock is intended for commercial-grade door installations where a classroom lockdown function is required. The outside lever is locked or unlocked by key, keeping occupants able to exit freely at all times while controlling outside entry. Typical installations include K-12 classrooms, college lecture halls, medical exam rooms, and similar institutional spaces where ANSI classroom function hardware is specified by code or facility standard.

Installation Notes

Mortise locks are installed by licensed locksmiths or qualified door hardware specialists. The door must be prepped with a mortise pocket sized to accept the lock body before installation begins. Verify the door thickness, backset, and handing before starting work, and confirm the strike and front plate align with the door frame cutout. Always confirm the cylinder and trim are fully seated and all screws are torqued before returning the door to service.
