Schlage Commercial 12-294 - B500 Series Deadbolt Adjustable 2-3/8" or 2-3/4" Backset, 1" x 2-1/4" Face, UL Listed, Fire Rated

One part covers both. The 12-294 bolt adjusts between a 2-3/8 inch and a 2-3/4 inch backset, so you don't have to measure the cross bore center before you order. Those two are the only backsets you'll normally meet on a bored door, which means a building with mixed prep across its openings can stock this single part number instead of two.

Just the bolt. The 12-294 is the replacement deadbolt latch that sits in the edge of the door, with a stainless steel body and a 1 x 2-1/4 inch face. There's no cylinder, no thumbturn and no strike in the box. Buy it when the existing bolt is seized, worn or the wrong backset, and reuse the cylinder and turn you already have on the door.

UL Listed and fire rated, so it can go back into a labeled opening. That covers the openings that usually decide this question in a commercial building: stair doors, corridor doors and apartment entries. It's a commercial-duty part in stainless steel, not a residential-grade bolt.

Check two things on the door edge. The 12-294 has a 1 x 2-1/4 inch face, which is the standard square face mortise on a bored deadbolt prep, and the bolt itself adjusts to either a 2-3/8 or 2-3/4 inch backset. If your existing bolt measures the same at the face and your cross bore centers at one of those two backsets, the new bolt goes straight in with the original screws and no new routing.

Match it. Schlage parts of this kind are finish specific, and the face plate stays visible on the edge of the door once the door is open, so a mismatch shows. The 12-294 comes in 626 satin chrome and 605 bright brass. Pull the old bolt and read the finish code off your existing trim before you order, particularly if you're doing a run of doors that need to look the same.

No. The 12-294 is a deadbolt bolt, so it throws a solid bolt with no bevel and no spring return, and it will not work in a knob or lever prep that needs a latchbolt. For a keyed entry latch, the Deltana G1RLE238 covers a 2-3/8 inch backset and the G1RLE275 a 2-3/4 inch backset, both Grade 1 entry function. If the door is a passage or privacy opening, the equivalents are the Deltana G1RLP238 and G1RLP275.

The 12-294 only helps if you're keeping the Schlage S200 or B500 lock and swapping the bolt. If the whole lock is coming off, the Lockey M230 is a complete keyless mechanical combination lock with a deadlocking spring latch and an adjustable backset, and it fits doors from 1-1/8 to 2 inches thick. That's the route to take when you also want to get rid of keys across a set of doors instead of rekeying them.

Two of them carry it, for two different parts of the opening. The Schlage 12-294 is UL listed and fire rated, and it is the deadbolt latch inside a S200 or B500 series lock on the door leaf itself, adjustable to a 2-3/8 inch or 2-3/4 inch backset behind a 1 inch by 2-1/4 inch face. The Accentra YSSL10 is also fire rated, but it is a security sidelite auxiliary latch with an ADA compliant thumbturn, sized for a 1-3/4 inch door thickness. That one mounts in the narrow sidelite panel and comes with its own thumbturn for operation, so it secures the fixed panel rather than replacing a bolt inside an existing deadbolt. On a storefront with an active leaf and a sidelite, the two do separate jobs on the same opening.

No, they serve two different bores in the door. The Schlage 12-294 is the deadbolt latch for the S200 and B500 series, adjusting between a 2-3/8 inch and 2-3/4 inch backset behind a 1 inch by 2-1/4 inch face, in stainless steel. The Deltana G1RLE238 is a Grade 1 regular latch in the Entry function on a fixed 2-3/8 inch backset, and its companion G1RLE275 is the same Grade 1 Entry latch on a 2-3/4 inch backset. A regular latch is the beveled spring latch retracted by the knob or lever, so it belongs in the latch bore of a keyed lockset. The 12-294 throws a deadbolt from the deadbolt bore above it, with no spring return and no knob to retract it.

The Schlage 12-294 adjusts to either a 2-3/8 inch or a 2-3/4 inch backset, so one deadbolt latch covers both hole patterns for S200 and B500 series locks, and it stocks in 626 satin chrome and 605 bright brass. The Lockey M230 is also built around an adjustable backset, though it arrives as a complete mechanical keyless combination lock with a deadlocking spring latch rather than a bolt on its own. Deltana splits its regular latches by backset instead: the Entry function is G1RLE238 at 2-3/8 inches and G1RLE275 at 2-3/4 inches, and the Passage/Privacy function is G1RLP238 at 2-3/8 inches and G1RLP275 at 2-3/4 inches, all four listed as Grade 1. With Deltana you carry the pair; with the 12-294 you carry the one.

The Schlage 12-294 is the replacement deadbolt latch for S200 and B500 series locks and keeps the opening keyed the way it is now, adjusting to a 2-3/8 inch or 2-3/4 inch backset and available in 626 satin chrome and 605 bright brass. If the goal is to stop issuing keys altogether, the Lockey M230 is a mechanical keyless digital combination lock with a deadlocking spring latch and an adjustable backset, fitting doors from 1-1/8 inches to 2 inches thick. It runs on a punched code with no battery and no cylinder, and it swaps the entire lock rather than the bolt inside the one already hung, so plan on a full lock change and a code handoff instead of a parts swap.

A privacy opening takes a latch built for that function. Deltana lists the G1RLP238 as a Grade 1 regular latch in the Passage/Privacy function on a 2-3/8 inch backset, with the G1RLP275 covering the same function on a 2-3/4 inch backset. Those retract from a knob or lever with a thumbturn on the occupied side. The Schlage 12-294 is the deadbolt latch for S200 and B500 series locks, adjustable to 2-3/8 inches or 2-3/4 inches with a 1 inch by 2-1/4 inch face, and it throws a bolt that has to be driven from a cylinder or turn on its own bore. Measure the backset before ordering the Deltana part, since the function and the backset are fixed together in its part number.

The names run close together but the parts do not cross. The Dexter deadlatch is made for the C1000 series and belongs in that lockset's latch bore. The Schlage 12-294 is the deadbolt latch for the S200 and B500 series, stainless steel, with a 1 inch by 2-1/4 inch face and a backset that adjusts to 2-3/8 inches or 2-3/4 inches, UL listed and fire rated. A deadlatch is the spring latch of a keyed knob or lever assembly; a deadbolt latch is the square bolt that sits in its own bore above it. Match the part to the series stamped on the lock you are servicing rather than to the word on the box.
