Schlage Commercial 30001S123626118 Mortise Cylinder S123

Product Description

The SCHLAGE COMMERCIAL 30001S123626118 is a 1-1/8 inch mortise cylinder designed for commercial and institutional door hardware applications. It features the S123 keyway, a keyed-different (KD) configuration, and ships with a compression ring, spring, and L cam included. The satin chrome finish provides corrosion resistance suited to high-traffic environments. This cylinder is installed by commercial locksmiths and door hardware technicians as a direct component within mortise locksets, replacing worn or rekeyed cylinders in access control upgrades or routine maintenance. At 0.4 pounds, it is a compact, single-unit replacement part.

This mortise cylinder is intended for commercial, institutional, and multi-family building applications where mortise-style locksets are the standard hardware specification. The S123 keyway restricts key duplication and is commonly used in master-key systems. The included compression ring, spring, and L cam make this a ready-to-install cylinder without the need to source ancillary hardware separately. Typical installation scenarios include office buildings, schools, healthcare facilities, and other commercial properties requiring controlled access on interior and exterior doors.
