Corbin Russwin CL3857NZD626 Storeroom Lever Lock

Product Description

The CORBIN RUSSWIN CL3857NZD626 is a Grade 2 standard-duty storeroom lever lock designed for commercial and institutional door hardware applications. It features a Newport lever paired with a D rose trim and operates as a single-cylinder storeroom function, meaning the exterior lever is always locked and entry requires a key while the interior lever remains free for egress. The lock uses an L4 keyway and ships in a satin chrome (626) finish. At 1.7 pounds, it is a compact, professional-grade unit suited for light commercial service.

This lock is suited for storeroom and supply-room doors in commercial buildings, schools, healthcare facilities, and institutional environments where controlled entry is required on one side while unrestricted exit must be maintained on the other. The Newport lever and D rose combination provides a clean, classic profile that fits standard commercial door preps. It is sold individually and typically installed by a licensed locksmith or commercial door hardware technician.
