Corbin Russwin ML2051NSM626M31 Office Mortise Lock

Product Description

The CORBIN RUSSWIN ML2051NSM626M31 is a single cylinder office mortise lock with Newport lever trim and M escutcheon, finished in satin chrome (626). Mortise locks of this type are engineered for commercial and institutional door applications where durability and security are required. The assembly includes the lock body, trim, and escutcheon as a working unit, allowing installation-ready deployment. Licensed locksmiths, commercial door hardware installers, and facility maintenance teams typically specify this product for office-function applications where the latch retracts by lever from both sides and the cylinder locks the outside lever.

This mortise lock is suited for commercial and institutional facilities including office buildings, schools, healthcare facilities, and government buildings. The office function allows free egress from the inside at all times while the outside lever can be locked or unlocked with a key, making it appropriate for individual office doors, private offices, and interior access-controlled entries. The Newport lever design and M escutcheon are standard trim options within the CORBIN RUSSWIN ML2000 series product line.

Installation Notes

Mortise lock installation requires preparation of the door edge and face for the mortise pocket, strike, and trim bores — work typically performed by a licensed locksmith or commercial door hardware installer. Power down any electrified hardware or access control components on the door before beginning work. Follow ANSI A156.13 standards and applicable local building codes when specifying and installing mortise hardware. Verify door thickness, backset, and handing compatibility with the lock body before installation.
