Schlage Commercial 12-287 Deadbolt, B500 Series, Triple Option, Adjustable 2-3/8" or 2-3/4" Backset, Square Corner, 1/4" Round Corner and Circular Drive-In Faceplates

One part covers both. The 12-287 is the adjustable backset bolt for Schlage B500 Series deadbolts, and it sets to either 2-3/8 or 2-3/4 inches, which are the two backsets doors get bored for. Measure from the door edge to the center of the bore and set the bolt to match the prep that is already there. Because it adjusts, a property manager carrying one part number can cover a building where some openings were bored at 2-3/8 and the rest at 2-3/4.

Match whatever is already cut into the door edge. The 12-287 is a triple option bolt and comes with all three: a square corner faceplate for a squared mortise, a 1/4 inch radius round corner faceplate for an edge routed with a standard corner cutter, and a circular drive-in collar for a door bored straight through the edge with no mortise at all. On a repair you are not picking a style, you are matching an existing cutout, so pull the old bolt and look at the edge before you commit to one.

That is what this part is for. The 12-287 is a factory replacement bolt for the Schlage B Series deadbolt, so the cylinder, the keying and the outside trim all stay in the door and nothing goes back to the keying bench. Two screws in the edge faceplate, pull the old bolt, set the new one to the same backset, reinstall. On a master keyed building that is the difference between a ten minute repair and pulling a cylinder back into the system.

It shows. The faceplate sits on the door edge and is visible any time the door is open, and Schlage builds these bolts finish specific rather than as one universal part. Six finishes are available: 605 bright brass, 609 antique brass, 612 satin bronze, 613 oil rubbed bronze, 619 satin nickel and 626 satin chrome. Order to the finish code of the deadbolt you are repairing so the edge plate reads the same as the rest of the trim on the opening.

Stainless steel, and it is the commercial B500 Series part rather than a residential component. Stainless is what you want on an exterior opening: the bolt and its faceplate take weather every time the door swings, and stainless does not corrode the way a plated steel part does once the plating wears at the throw. On a multi-family entry or an MRO opening cycled all day, a corroded or galled bolt is usually the exact failure being replaced.

Bolt only. It is the assembly that throws into the strike, sold as a replacement for B500 Series deadbolts, and there is no cylinder, key or thumbturn in the box. If the opening has no lock in it yet, this is the wrong part. For a complete keyless unit instead of a component, the Lockey M230 is a mechanical combination deadlocking spring latch lock with an adjustable backset that covers doors 1-1/8 to 2 inches thick.

They are not the same part doing the same job. The Deltana G1RLE238 is a Grade 1 regular latch with an Entry function built to a 2-3/8 inch backset, and its 2-3/4 inch backset counterpart is the G1RLE275 - those are the spring latches that retract when the knob or lever is turned. The Schlage 12-287 is a B500 Series replacement part for a Schlage B Series deadlatch, so it goes back into the deadbolt it serves rather than into a knob or lever prep. On a door that has a Schlage B500 deadbolt above the lockset, the 12-287 is the part that matches the deadbolt and a Deltana entry latch serves the lockset below it.

A sidelite is a different opening and takes a purpose-built auxiliary latch rather than a service part pulled from a full-size deadbolt. The Accentra YSSL10 Security SideLite Auxiliary Latch is made for that panel, comes with an ADA compliant thumbturn, is fire rated, and is built for a 1-3/4 inch door. The Schlage 12-287 belongs in the main leaf: it is the B500 Series replacement part for a Schlage B Series deadlatch, so it is what you order when the deadbolt in the active door needs new internals rather than when the sidelite needs to be locked.

No - a deadlatch service part follows the lock series it was built for, so these are two separate line items. The Dexter deadlatch for the C1000 Series is ordered as DEXC1000-DL-630 and is listed at Grade 2. The Schlage 12-287 is the B500 Series part, a stainless steel commercial replacement for a Schlage B Series deadlatch, and it comes in 605 Bright Brass, 609 Antique Brass, 612 Satin Bronze, 613 Oil Rubbed Bronze, 619 Satin Nickel and 626 Satin Chrome so it can be matched to the finish already on the door.

There is, but it changes the lock rather than repairing it. The Lockey M230 is a mechanical keyless digital combination deadlocking spring latch lock with an adjustable backset, and it is built for doors 1-1/8 to 2 inch thick - you push a code instead of carrying a key, and the whole lock comes off the door and goes back on. The Schlage 12-287 takes the other route: it is a B500 Series replacement part for a Schlage B Series deadlatch, in stainless steel, so the existing B500 deadbolt and its keys stay in service and only the internals are renewed.
