Corbin Russwin ML2051NSA626M31 Mortise Lock Satin Chrome

Product Description

The CORBIN RUSSWIN ML2051NSA626M31 is a single cylinder office mortise lock with working trim, featuring the Newport lever style on an A Rose trim plate in a satin chrome finish (626). Mortise locks are the commercial standard for medium- to high-traffic door openings in office, institutional, and light industrial applications. The ML2051 function provides single cylinder office lockup, allowing free egress from the inside while controlling entry from the outside. Licensed locksmiths, commercial door hardware specialists, and general contractors typically handle installation of mortise lock sets in new construction and retrofit projects.

This mortise lock assembly is suited for commercial and institutional interior doors where a professional-grade cylindrical trim and durable lockbody are required. The 626 satin chrome finish provides a clean, low-glare appearance consistent with commercial hardware standards. The Newport lever design and A Rose trim configuration make this unit appropriate for office suites, administrative areas, and similar controlled-access spaces. The unit ships as a single assembly (sold individually).

Installation Notes

Mortise lock installation should be performed by a licensed locksmith or qualified commercial door hardware technician. The door must be properly mortised to accept the lockbody before hardware is fitted — confirm pocket dimensions match the lockbody before beginning. Disengage all power to any integrated access control or electrified hardware prior to service. Consult applicable local building codes and ANSI/BHMA standards for commercial door hardware installation requirements.
