Medeco³ Rim & Mortise

Medeco® Rim and Mortise cylinders provide patented key control and UL437 Physical Security in adaptable retrofit cylinder formats.

Medeco® Mortise cylinders have threads on the outside of the shell and are designed to be screwed into other manufacturer's mortise lock cases. A cam on the back of the cylinder operates the lock mechanism and a set screw holds the mortise cylinder in place. Medeco®Rim cylinders are used with auxiliary rim locks such as: surface mounted deadbolts, night latches, panic devices and jimmyproof locks (also know as vertical dropbolts or interlocking deadbolts).

Rim cylinders are held in place with a back plate and two mounting screws.

10 series, rim and mortise cylinders, are UL437 listed for drill and pick resistance, and the those that incorporate the Biaxial® design, offer utility patented key control.

Rim and Mortise cylinders can be ordered with a variety of different cylinder technologies, including the features below for Medeco³.
