Commercial Lock Cylinders | Mortise, Rim & Interchangeable Cores
Ensure the integrity of your facility with professional-grade commercial lock cylinders and replacement interchangeable cores. From threaded mortise cylinders for storefronts to SFIC and LFIC cores for campus-wide security, these solutions provide the precise control required for modern access management. Engineered for durability and compatibility, these cylinders integrate seamlessly into existing hardware from Sargent, Accentra, and other leading manufacturers to meet rigorous life-safety and security standards.
IC Tailpieces
IC tailpieces are the critical mechanical link between an interchangeable core and the internal lock chassis. Because tailpiece requirements vary by lock brand and door thickness, using a brand-specific tailpiece is mandatory for smooth operation. These precision-engineered components ensure that the rotation of the key correctly retracts the latch or deadbolt.
- Best For: Maintaining or repairing IC core installations in various lever and knob sets.
Interchangeable Core Housings (Mortise and Rim)
IC housings serve as the permanent "shell" in a door, allowing for the use of interchangeable cores. By installing mortise or rim IC housings, facilities can transition to a rapid re-keying system without ever removing the housing from the door. These are essential for high-turnover environments like retail centers or healthcare facilities.
- Best For: Facilities that require frequent re-keying without removing the entire lock.
Interchangeable Cores
Interchangeable cores (IC), including Small Format (SFIC) and Large Format (LFIC), allow for instantaneous security updates. Solutions from Accentra (formerly Yale) and Sargent enable a "control key" to pull the core and replace it in seconds. This eliminates the need for a locksmith to disassemble the lock, making them the premier choice for large-scale master key systems.
- Best For: Hospital campuses, universities, and multi-tenant commercial buildings.
Conventional Cylinders
Conventional cylinders (often called Key-in-Knob or Key-in-Lever) are the standard for most commercial office doors. These cylinders are integrated directly into the lever or knob assembly and are used for basic access control where quick re-keying isn't a daily requirement.
- Best For: Interior office doors and standard duty cylindrical locks.
Rim Cylinders
Unlike threaded mortise versions, Rim cylinders are held in place by long mounting bolts and a backplate. They feature a long, flat tailpiece that protrudes from the back of the cylinder to reach the locking mechanism. These are most commonly found on the exterior side of "panic hardware" or exit devices.
- Best For: Exit devices (panic bars) and fire-rated rim exit hardware.
Mortise Cylinders
Mortise cylinders are threaded units designed to screw directly into a mortise lock body. They are recognized by their circular shape and the "cam" on the back that rotates to activate the lock mechanism. They offer superior physical security for exterior entries and high-traffic commercial aluminum storefront doors.
- Best For: Storefront doors, school classrooms, and high-security hollow metal doors.
