Schlage Commercial 12-288 Deadbolt, B500 Series, Adjustable 2-3/8" or 2-3/4" Backset, 1" x 2-1/4" Face, Square Corner

Yes. The 12-288 is a genuine Schlage replacement latch for the B500 Series deadbolt, and it also covers S200 Series. It replaces the bolt assembly inside the door edge, not the outside cylinder or the inside thumbturn, so if your problem is a sticking or worn bolt this is the piece you need. If the key won't turn or the cylinder is damaged, that is a different part.

It's a deadbolt. The bolt only moves when the key or thumbturn is turned, so it will not hold a door closed by itself and it does not latch when you pull the door shut. You still need a knob or lever latchset on the door for normal closing. If what you actually want is a bolt that springs into the strike as the door closes, look at a regular latch instead, such as the Deltana G1RLE238 entry latch for a 2-3/8 backset or the G1RLE275 for 2-3/4.

The Schlage 12-288 covers it without a second part number. Its backset is adjustable to either 2-3/8 inch or 2-3/4 inch, so one latch fits both door preps. The Deltana Grade 1 regular latches are split by backset instead, with the G1RLE275 built for 2-3/4 inch entry and the G1RLE238 for 2-3/8 inch, so with those you order the backset you measured. If you are stocking a truck or a fleet of buildings with mixed preps, the adjustable Schlage part means one SKU on the shelf covers both.

No. The Dexter Grade 1 Deadlatch is built for the Dexter C1000 Series and carries a Grade 2 rating, while the Schlage 12-288 is a certified Schlage replacement part for the S200 and B500 Series. Latches of this kind are keyed to the chassis they ship with - face size, corner shape, and tailpiece engagement are series specific. If the lock in the door is a Schlage B500, the 12-288 is the matching part; the Dexter deadlatch belongs in a C1000 chassis.

For most jobs, no. The only visible piece is the faceplate on the door edge, which is hidden when the door is closed. But Schlage parts are frequently finish specific, so if you are standardizing a building and want the edge plate to match the rest of the trim, order the finish that matches. Six are offered: 605 bright brass, 609 antique brass, 612 satin bronze, 613 oil rubbed bronze, 619 satin nickel, and 626 satin chrome.

It's a commercial-duty part. The bolt assembly is stainless steel and the 12-288 is catalogued on the commercial side of Schlage's line, matched to the B500 Series. That's the material you want on a door cycled all day in an apartment building, office, or school, where a plated pot-metal bolt wears loose.

For a keyless opening on the same kind of prep, the Lockey M230 is a mechanical combination deadlocking latch lock with an adjustable backset, rated for doors 1-1/8 to 2 inches thick. It's a complete lock rather than a replacement bolt, so it is the route when you're changing how the door is operated rather than repairing an existing Schlage B500. If you're keeping the Schlage deadbolt and only fixing the bolt, the 12-288 is the part.

For a passage or privacy opening, look at the Deltana Grade 1 regular latches in that function - the G1RLP238 on a 2-3/8 inch backset and the G1RLP275 on a 2-3/4 inch backset. The Schlage 12-288 is a deadbolt latch for the B500 Series, so it belongs in a door that has a separate deadbolt bore and a bolt thrown by key or thumbturn. A bathroom, office, or bedroom door with a single bore and no keying takes the passage/privacy latch instead.

The 12-288 is a latch component only - it is the bolt and face for a Schlage B500 Series deadbolt, and the credential is whatever cylinder or thumbturn drives it. For keyless, the Lockey M230 is a complete mechanical keyless digital combination lock with a deadlocking spring latch and an adjustable backset, so the code pad and the latch come together as one unit. Choose the M230 when you want to stop issuing keys entirely; choose the 12-288 when the B500 lock stays in the door and only the latch is being replaced.

The Deltana regular latches carry a stated Grade 1 rating across all four - G1RLE238 and G1RLE275 in entry function, G1RLP238 and G1RLP275 in passage/privacy - split by 2-3/8 inch and 2-3/4 inch backset. The Dexter C1000 Series deadlatch is Grade 2. The Schlage 12-288 is the certified Schlage replacement latch for S200 and B500 Series openings, in stainless steel, so it is the standardization answer where the building is already on Schlage B500 hardware and you are matching the existing lock rather than converting the doors.

Yes - Schlage parts of this kind are finish specific, and the 12-288 comes in 605 Bright Brass, 609 Antique Brass, 612 Satin Bronze, 613 Oil Rubbed Bronze, 619 Satin Nickel, and 626 Satin Chrome so the face plate matches the lock already in the door. That finish match is the reason to stay with the Schlage part on a B500 opening rather than crossing to another maker's latch: the Deltana regular latches and the Dexter C1000 deadlatch are matched to their own chassis and trim, not to Schlage's finish numbers.
