Schlage Commercial 26091C626 Mortise Cylinder C Keyway

Product Description

The SCHLAGE COMMERCIAL 26091C626 is a full-size interchangeable mortise cylinder designed for commercial and institutional door hardware applications. It features a C keyway configuration and ships 1 bitted, meaning the cylinder arrives pre-keyed to a specific key cut. The unit includes a compression ring, spring, and K510-730 cam, giving installers a complete, ready-to-mount assembly. Finished in satin chrome, it suits commercial doors where a clean, low-glare appearance is specified. The cylinder measures 3.5 inches in length, 2.3 inches in width, and 1.6 inches in height, fitting standard mortise lockbody cutouts found across commercial construction.

This mortise cylinder is suited for commercial, institutional, and multi-family residential door applications where an interchangeable core system is not required but a durable, field-rekeyable cylinder is. Typical installations include office entry doors, corridor doors, and stairwell hardware. The C keyway limits key duplication to authorized channels, which is a common requirement in access-control specifications for schools, healthcare facilities, and office buildings. Locksmiths and commercial door hardware installers handle replacement and new-installation work on these cylinders.

Installation Notes

Installation is performed by a licensed locksmith or qualified commercial door hardware technician. Before servicing, confirm the door is in an unlocked, secured-open position and that any access control wiring tied to the lockset is de-energized. Use the correct cam orientation for the handed lockbody before seating the cylinder to avoid damage to the tailpiece or cam. Follow ANSI A156.30 and applicable building or fire-code requirements for egress hardware when specifying or replacing mortise cylinders on rated doors.
