Brass Mortise Cylinder Collar Guard

The Em-D-Kay SPC3 is a brass spring-type cylinder collar guard designed for mortise lock cylinders. It functions as a free-spinning ring that prevents intruders from gripping and forcibly unscrewing the lock cylinder with tools like channel locks or vise grips. This hardware adds a layer of physical security to compatible door locks.

Check Cylinder Type And Finish

Verify that your existing lock uses a mortise cylinder, as this guard is specifically designed for that cylinder type. Confirm that the bright brass finish matches your current door hardware for a consistent appearance. Ensure the cylinder dimensions allow the guard to sit flush and spin freely without binding against the door face or escutcheon.

Fits Mortise Lock Assemblies

The guard installs around the mortise cylinder, sitting between the cylinder head and the escutcheon or door surface. Its internal spring maintains tension to keep the collar spinning freely during an attack attempt. The package includes one cylinder guard with the spring mechanism. It requires no modification to the lock body itself and works with standard mortise lock trim.
