Dormakaba QDB281-626 Sfic Deadbolt Single Cylinder Satin Chrome

Product Description

The DORMAKABA COMMERCIAL HDWE QDB281-626 is a single-cylinder SFIC (Small Format Interchangeable Core) deadbolt designed for commercial door hardware applications. It features a 2-3/4 inch backset and ships with a square deadbolt strike, finished in satin chrome. The SFIC core format allows authorized personnel to swap cores without removing the lock from the door, making it well-suited for facilities that require frequent rekeying or master-key system management. Licensed locksmiths and commercial door hardware installers are the primary tradespeople who specify and install this unit.

This deadbolt is appropriate for commercial and institutional facilities including office buildings, schools, healthcare facilities, and multi-tenant properties where access control and key-system flexibility are priorities. The single-cylinder format operates with a key on the exterior and a turn piece on the interior. Its satin chrome finish coordinates with standard commercial hardware trim. The included square strike fits standard commercial door frames prepared for auxiliary deadbolt hardware.
