Cylinder Collar Guard for Mortise Locks

The Em-D-Kay SPC2 is a satin chrome cylinder collar guard designed for mortise cylinders. It acts as a free-spinning ring that prevents intruders from gripping and unscrewing the lock cylinder with common burglary tools. The unit is supplied new and includes the guard, a spring, and a washer for installation.

Spring-Loaded Free-Spinning Resistance

Under sustained attack the collar rotates freely when gripped by channel locks or vise grips, denying the leverage needed to twist the cylinder out of the door. The internal spring maintains constant tension against the lock face, keeping the guard seated and operational throughout prolonged manipulation attempts without binding or loosening.

Verify Mortise Cylinder Dimensions

Confirm that the existing mortise cylinder diameter and thread pattern match the guard's internal bore before ordering. Check that the cylinder protrudes far enough from the door face to accommodate the guard's depth and the included washer. Ensure the spring mechanism has clearance to compress fully against the lock housing without obstruction from surrounding trim or escutcheons.

Questions about this item

Does the Em-D-Kay SPC2 cylinder collar guard generate any noise or heat when installed on a mortise lock?

No, the SPC2 is a passive mechanical guard with a spring-loaded free-spinning ring; it has no moving parts that create noise, draws no power, and produces no heat during continuous use.

What existing hardware must already be on the door for the SPC2 to function?

A mortise lock cylinder is required; the collar slides over the cylinder and secures with the included spring and washer, so the lock body and cylinder must already be fitted in the door.

Will the SPC2 satin chrome collar fit older mortise cylinders that have a slightly different diameter?

The guard is designed for most standard mortise cylinders; its spring-loaded design accommodates typical cylinder dimensions, but cylinders outside the usual range may not engage the spring correctly.
