Dormakaba QTL250E626-SA-478S-SCKD Entry Office Lever Lock

Product Description

The DORMAKABA QTL250E626-SA-478S-SCKD is a Grade 2 cylindrical lever lock designed for light commercial door applications. It features the Sierra bent lever profile on a small rose, a 6-pin Schlage C keyway cylinder, and a keyed-different configuration. The adjustable square latchbolt accommodates doors ranging from 1-3/8 inches to 1-3/4 inches thick, and the lock ships with a 4-7/8 inch by 1-1/4 inch ANSI strike. The finish is 626 Satin Chrome. This lock is part of the QTL series and is intended for installation by licensed locksmiths or commercial door hardware professionals on standard-duty entry and office doors.

This lock is suited for light commercial environments where Entry or Office function is required. The Entry function allows outside lever access by key and free egress from inside. The Office function keeps the outside lever locked at all times, with access by key only. Typical installations include office suites, tenant entries, light commercial storefronts, and interior doors requiring controlled access. The adjustable backset and compatibility with standard door prep dimensions make this a practical choice for new construction and retrofit projects on doors from 1-3/8 inches to 1-3/4 inches thick.

Installation Notes

Installation should be performed by a licensed locksmith or qualified door hardware technician familiar with ANSI cylindrical lock prep standards. Confirm door thickness and backset before installation, as improper backset selection will affect latch and strike alignment. Verify that the door and frame meet the requirements of the applicable fire rating if installed in a rated opening. Do not force the lever or latchbolt assembly during installation, as this may damage the deadlatch mechanism.
