Dormakaba QTL270E626-SA-478S-SCKD Storeroom Lever Grade 2

Product Description

The DORMAKABA QTL270E626-SA-478S-SCKD is a storeroom-function cylindrical lever lock from the QTL200 series, engineered for light commercial door hardware applications. It features a Sierra bent lever with a small rose, a 6-pin Schlage C keyway cylinder, and a keyed-different configuration. The adjustable square latch is a deadlatch type with a 2.75-inch backset. The lock is finished in 626 Satin Chrome and is built to meet Grade 2 performance standards. Licensed locksmiths, commercial door hardware installers, and general contractors are the primary trades that specify and install this hardware.

This lever lock is suited for storeroom doors in light commercial environments such as offices, retail spaces, schools, and similar facilities. The storeroom function keeps the outside lever locked at all times, requiring a key for entry, while the inside lever remains free for egress. The adjustable backset accommodates doors of varying thickness from 1.375 inches to 1.75 inches, making it practical for both new construction and retrofit applications. The Schlage C keyway allows integration into existing Schlage-compatible keying systems where keyed-different cylinders are specified.
