The SCHLAGE COMMERCIAL 40100C135626 is a replacement cylinder with multiple tailpieces, designed for commercial and institutional door hardware applications. It features the C135 keyway and is supplied 0 bitted, meaning it arrives without any cuts and must be keyed to specification by a licensed locksmith or facilities technician. The satin chrome finish provides a clean, low-glare appearance suited to professional environments. At 0.25 pounds, the cylinder is compact and built for direct installation into compatible locks and trim assemblies.
This cylinder is intended for commercial, institutional, and multi-family building applications where field-keying flexibility is required. The 0 bitted configuration allows the installer or locksmith to key the cylinder to a master key system or standalone key specification on-site. Multiple tailpieces are included to accommodate a range of lock body configurations, making this cylinder adaptable across a variety of door hardware setups encountered in commercial service work.
Designed as an OEM-style replacement cylinder for commercial door lock assemblies requiring a C135 keyway profile with multiple tailpiece support.
Cylinder replacement and keying should be performed by a licensed locksmith or qualified facilities technician familiar with commercial lock hardware. Verify the keyway and tailpiece configuration match the existing lock body before installation. Consult applicable local building and life-safety codes when servicing hardware on egress or fire-rated doors. Remove the lock from service and ensure all keys are accounted for prior to beginning cylinder work.
