For new construction or retrofits, Grainger has a wide selection of door lock cylinders to help keep locations and contents safe and secure. Interchangeable core cylinders can provide moderate resistance against manipulation and forceful attack. Unlike standard key cylinders, an interchangeable mechanism relies on a control key for insertion and extraction of the essential (core) combining components. They can be adapted to master keying systems and can also be set up with spare cores and keys for quick replacement when security is compromised. Interchangeable core cylinders are available in several finishes and keyway types. Tough brass cylinder locks allow easy change-out without altering the boltwork hardware. You can choose from a range of lock finishes and keyway types to meet most applications.
