Adams Rite Cylinder guard & retaining ring

Product Information

Used with round screw in cylinder for added security.

As a standard mortice cylinder is made of brass, it is a potential weak point in narrow stile door security. The MS®4043
offers three forms of defence against somebody trying to prise the cylinder out of the door:
1. Outer shield ring is fully bevelled to offer poor grip for prying or twisting.
2. The ring is manufactured from hardened steel, and coupled with its shape makes gripping the ring tightly
virtually impossible.
3. If a tool such as a cold chisel is driven into the stile behind the shield ring, the cylinder is still protected by
the retainer plate, which would have to be pulled through a round hole in the metal door stile.
This degree of leverage would be impossible with most hand tools.
