Accepts interchangeable cores (not included). This housing comes standard to accept Small Format Interchangeable Cores (SFIC), which is a common size used by many brands. If you know that you'll be using Large Format Interchangeable Cores, please specify LFIC and the brand in the options when ordering.
Rim cylinders are used in situations where the lock is not embedded within the door. For example, in the cases of deadbolts or locking pulls. To learn more about which types of doors a rim cylinder will work with, read our article here: Which Locks Work with Which Hardware
