What is a rim cylinder?
A rim cylinder is a surface-mounted mortise rim cylinder typically installed on doors with rim exit devices or night latches. It mounts through the door and connects to the locking mechanism inside, often used with ic core housing for commercial security upgrades.
What is an IC core cylinder?
An IC core cylinder (interchangeable core cylinder) is a lock system where the core can be removed and replaced using a control key without removing the entire cylinder housing. This design simplifies rekeying in commercial buildings using ic core systems.
What is the difference between a cylinder and a core?
The cylinder refers to the complete lock body, including the cylinder housing, while the core is the removable internal component containing pins and keyway. In an ic cylinder, the core can be swapped independently from the housing.
What is the cylinder in a lock?
The cylinder in a lock is the mechanical component that houses the pins and plug where the key is inserted. In commercial setups, a mortise rim cylinder may contain an ic core cylinder for faster rekeying and maintenance.
What is the difference between SFIC and LFIC cores?
SFIC (Small Format Interchangeable Core) and LFIC (Large Format Interchangeable Core) differ in size and manufacturer compatibility. SFIC fits standardized ic core housing, while LFIC is brand-specific, often found in Schlage IC core cylinder systems and other proprietary formats.
What are type 4 cylinders?
Type 4 cylinders typically refer to commercial-grade interchangeable core configurations used in master key systems. These IC cylinder setups are designed for durability, security compliance, and compatibility with professional cylinder housing installations.
How do I know if my door lock cylinder is bad?
