Cal-Royal CGR175-26D – Frequently Asked Questions

1) What does a free spinning cylinder guard ring like the Cal-Royal CGR175 actually do?
It sits around the mortise cylinder and spins freely, so anyone putting a pipe wrench or pliers on the cylinder just turns the ring instead of getting a bite on the cylinder body. That kills the common wrenching and twisting attack on an exposed mortise cylinder. The CGR175 ships with a spacing collar and a wave washer, which take up the slack behind the ring so it seats tight to the door face and still rotates.
2) Will the CGR175 guard ring work with my existing keying, or do I have to rekey the door?
Cylinders supplied with the CGR175 are drilled for 6 pins and can be keyed with your original pins, so they can be built to the original manufacturer's keying specification. For a property manager holding an existing master key system, that means the opening stays on the same key rather than becoming a one-off.
3) What size cylinder opening does the Cal-Royal CGR175 guard ring cover?
The CGR175 is a 1-3/4 inch wide ring. That is the outside diameter you are fitting to the door face around a standard mortise cylinder, so measure your existing escutcheon or ring footprint before you order a fleet of them.
4) Do I get everything I need to install the CGR175, or is there other hardware to order?
The ring comes with its spacing collar and wave washer, which is the stack you need behind the ring for correct projection and retention. What it does not include is the door itself being prepped for a mortise cylinder, and the cylinder length has to suit your door and trim thickness once the collar and ring are added, so check that the cylinder still threads far enough into the lock case.
5) Can I standardize on the CGR175 across a whole building's exterior doors?
That is the normal use for it. Because the cylinders are drilled for 6 pins and can be built to your existing keying specification, you can add the rings across a run of openings without breaking the master key system, and pick one of the three finishes to keep the doors consistent. It is a commercial-grade lock part, so it suits a fleet rollout on offices, schools or multi-tenant properties.
6) Is this guard ring meant for commercial doors or residential ones?
The CGR175 is a commercial-rated part, built for openings like offices, schools, healthcare, retail, warehouses, multi-tenant residential and municipal buildings. It will physically work on a residential door with a mortise cylinder, but it is specified for commercial traffic and commercial attack resistance.
7) Does the wave washer really matter, or can I leave it out?
Leave it out and the ring either binds or rattles. The wave washer provides the spring tension that keeps the guard ring pressed against the door face while still letting it spin, and the spacing collar sets the gap. Both are part of the CGR175 assembly and both belong in the stack for the free spinning action to work as intended.
