Product Description

The DORMAKABA COMMERCIAL HDWE 8Q00189-626 is a 2-3/8 inch square drive QCL 200 series deadlatch finished in satin chrome (626). Deadlatches provide automatic latch bolt retraction on door closing and positive locking engagement, making them a core component in cylindrical and tubular lockset assemblies for commercial door hardware installations. This unit ships as a single piece and is suited for licensed locksmiths, door hardware installers, and commercial construction trades working on light to heavy commercial applications where a reliable, code-compliant latch mechanism is required.

The 8Q00189-626 is intended for commercial door hardware applications where a square-drive deadlatch is specified. The QCL 200 series designation places this latch within a family of cylindrical lockset components commonly used in office, institutional, and light commercial door assemblies. The satin chrome finish provides a clean, low-sheen appearance consistent with 626-finish hardware specifications used across coordinated commercial hardware schedules.
