Product Description

The SCHLAGE COMMERCIAL 20001C626134 is a conventional mortise cylinder designed for commercial and institutional door hardware applications. Built at 1-3/4 inches in length, it features a C keyway profile and is supplied keyed different (KD), making it suitable for installations where unique key control is required across multiple openings. The cylinder includes a compression ring, spring, and straight cam, delivering a complete, ready-to-install assembly. Finished in satin chrome (626), it provides a clean, professional appearance compatible with standard commercial hardware. Licensed locksmiths, commercial door hardware technicians, and facilities maintenance professionals are the primary installers of this cylinder.

This mortise cylinder fits standard commercial mortise locksets that accept a conventional cylinder format with a straight cam configuration. The C keyway is a widely used profile in commercial keying systems, supporting master key hierarchies common in office buildings, institutional facilities, and multi-tenant commercial properties. The satin chrome finish coordinates with 626-finish hardware families. The included compression ring and spring ensure proper seating within the mortise lock body without requiring separate hardware procurement.

Installation Notes

Installation is typically performed by a licensed locksmith or qualified commercial door hardware technician. Before servicing any lockset, ensure the door is propped open and building access control procedures are followed to prevent lockout. The cylinder should be inserted with the cam oriented per the lock body manufacturer's specification before tightening the retaining screw. Verify key operation and cam engagement under both latch and deadbolt functions before returning the door to service.
