The SCHLAGE COMMERCIAL B520253 is an interchangeable core mortise cylinder cam designed to retrofit Corbin Russwin ML2200 series mortise locksets. The cam serves as the mechanical interface between the cylinder core and the lockset chassis, transmitting rotational input from the key cylinder to the bolt mechanism. This component is sold as a single unit and is intended for installation by licensed locksmiths or commercial door hardware technicians working on institutional and commercial door hardware. At 0.05 pounds, it is a lightweight precision component where exact fitment is critical to proper lockset function.
This cam is used in commercial and institutional settings where Corbin Russwin ML2200 series mortise locks are installed. Typical applications include office buildings, healthcare facilities, schools, and multi-family residential entry doors that use interchangeable core cylinder systems. The interchangeable core format allows facility managers and security professionals to rekey or swap cores without removing the entire lockset from the door, making this cam an important component in large-scale keying programs.
Designed for use with Corbin Russwin ML2200 series mortise locksets in interchangeable core cylinder configurations.
Installation should be performed by a licensed locksmith or qualified commercial door hardware technician. Before servicing, ensure the door is secured open and any access control power to the lockset is disconnected. The cam must be correctly oriented to the cylinder core before seating to ensure proper bolt actuation. Verify fitment and full bolt throw operation after installation before returning the door to service.
