Em-D-Kay Padlocks WSC3 Brass Cylinder Collar Guard with Spring & Washer

Brass cylinder collar guard

The Em-D-Kay WSC3 is a bright brass cylinder collar guard designed to protect lock cylinders on mortise locks. It fits most standard cylinders and ships as a single unit with a spring and washer included. The free-spinning ring stops intruders from gripping and unscrewing the cylinder with common burglary tools. This hardware suits homeowners and installers reinforcing existing door security.

Free-spinning protection limits

The guard prevents forced unscrewing by rotating freely when attacked with channel locks or vise grips. It does not stop lock picking, bumping, drilling or other non-rotational attack methods. Effectiveness depends on the cylinder protruding enough for the guard to engage and spin without binding against the door face or escutcheon. The bright brass finish matches traditional hardware but will patina over time.

Check cylinder fit before ordering

Verify that your cylinder diameter and projection match the guard's internal dimensions so the ring spins freely. Confirm the mortise lock body and door thickness allow the washer and spring to seat correctly without preventing the cylinder from operating. Ensure the existing cylinder collar or rose does not block installation or restrict the guard's rotation. The pack contains one guard, spring and washer only.
