GMS 1-1/8" Rim Cylinder, Schlage C Keyway, Keyed Alike in Pairs

The GMS R118 uses an Adams Rite and Yale cam, so it drives the tailpiece style those storefront and mortise-style locks expect. It's a 1-1/8 inch length cylinder with a solid brass body, and the tailpiece flips between horizontal and vertical positions, which is what lets it line up with either orientation of hardware without a separate part. If your opening takes an Adams Rite or Yale cam cylinder at 1-1/8 inches, this drops in.

Five keyway families are offered on the R118: Schlage, Kwikset, Corbin, Sargent, and Yale. Pick the one that matches the keys already in circulation on the building and the new cylinder joins that key system instead of adding a second key to everyone's ring. Each of those keyways is available in all three finishes.

They're keyed alike in pairs, so a pair comes cut to one key and each cylinder ships with 2 keys. That's the setup for a double-door entrance or a front and back door on the same unit, where one key should open both. It is not a building-wide master system: order a separate pair for each opening you want on its own key, or order everything in the same keyway family if you plan to have a locksmith re-pin them into one system later.

The R118 is offered cut to the Schlage C keyway, which is the standard commercial Schlage profile most buildings on Schlage keys are already using. A cylinder in that keyway will accept a Schlage C blank, so a locksmith can key it to your existing system. Out of the box it arrives keyed alike in pairs with its own keys, not cut to your key.

Conventional mortise classification, meaning it's a fixed pin-tumbler cylinder that a locksmith re-pins by hand. There's no removable core to pull with a control key. If your facility standardizes on SFIC so maintenance can swap cores on turnover without a locksmith, this is not that part and it won't accept an interchangeable core.

1-1/8 inch is the standard length for cylinders in aluminum storefront and most standard-thickness commercial doors, and that's what the R118 is. Thicker doors or applications where the cylinder sits behind added trim or an armored collar need a longer body, so measure from the face of the ring to the back of the cylinder on what you're pulling out. If the old one measures longer than 1-1/8 inches, this won't reach the cam far enough to drive the lock.

Three finishes: 613 oil rubbed bronze, 622 matte black, and 626 satin chrome. For a building already on oil rubbed bronze lever sets and pulls, 613 is the match. 626 satin chrome is the usual pairing with brushed or satin nickel commercial trim, and 622 matte black suits the black hardware packages common on newer storefront and multi-family work. All three are available in every keyway offered.

No handing to specify. The tailpiece converts between horizontal and vertical positions, so one cylinder covers either orientation the lock body needs, and the same part number works on a left hand or right hand door. What you do have to get right is the cam type, the keyway, and the 1-1/8 inch length.

Each cylinder is supplied with 2 keys, and the tailpiece is part of the cylinder. Keys are not an add-on. What is not included is the mounting hardware specific to your lock body (cylinder retaining screws or clamp plate typically stay with the existing lock), so plan on reusing what's in the door.

Solid brass construction is what you want on an exterior cylinder, brass doesn't rust and it machines tight enough to keep the plug turning smoothly after weather and grit. On finish, be aware that 613 oil rubbed bronze is a living finish that darkens and wears at the keyway with heavy use; on an entrance a hundred people key through daily, 626 satin chrome holds its appearance longer.
