Corbin Russwin CL3857NZD613 Storeroom Lever Lock Grade 2

Product Description

The CORBIN RUSSWIN CL3857NZD613 is a single cylinder storeroom lever lock designed for commercial and institutional door applications. It features the Newport lever style paired with a D rose trim and operates on the L4 keyway system. Rated Grade 2 Standard Duty, this lock is built for doors that require outside entry by key only, with a permanently locked latch from the outside — a configuration suited for storerooms, supply closets, and secured access points. The Oil Rubbed Bronze finish provides a consistent aesthetic for commercial hardware schedules. Installation is handled by licensed locksmiths or commercial door hardware technicians.

This lever lock is intended for commercial and institutional facilities where controlled storeroom-function access is required. The single cylinder format means keyed access from the exterior while the interior lever remains free-turning for egress. The Newport lever and D rose combination fits standard commercial door prep and is well-suited to offices, schools, healthcare facilities, and light institutional environments operating under Grade 2 duty requirements.
