Dexter Commercial C1000STRMC626KDC Grade 1 Cylindrical Lock

Product Description

The DEXTER COMMERCIAL C1000STRMC626KDC is a Grade 1 storeroom-function cylindrical lock featuring a curved lever with a clutching mechanism and satin chrome finish. Built for demanding commercial environments, it operates on a 2-3/4 inch backset with a 1-1/8 inch face and ships with an ANSI-standard strike plate. The C keyway provides controlled key access, and the storeroom function keeps the outside lever locked at all times — entry is granted only by key, making it well suited for secure storage and access-controlled spaces. Licensed locksmiths and commercial door hardware installers are the primary tradespeople handling this unit.

This lock is intended for commercial interior doors requiring constant security — storerooms, supply closets, server rooms, and similar access-controlled applications. The Grade 1 ANSI rating indicates the highest classification for duty cycle and strength testing, making it appropriate for high-traffic facilities such as office buildings, schools, healthcare facilities, and retail environments. The clutching lever prevents forced lever rotation, adding a layer of mechanical security beyond a standard cylindrical lock.

Installation Notes

Installation should be performed by a licensed locksmith or qualified commercial door hardware technician familiar with ANSI cylindrical lock prep standards. Verify door thickness, backset measurement, and bore diameter before installation to confirm fitment. Ensure the door is held stationary and all latching components are properly aligned before securing the lock body. Consult local building and fire codes for egress requirements before specifying storeroom-function hardware on any path of egress.
