Schlage Commercial 12-100 Deadlatch, B250 Series, 2-3/8" Backset, 1-1/8" x 2-1/4" Face

Deltana covers that prep directly: the G1RLE275 is a Grade 1 regular latch with an entry function at 2-3/4 inch backset, and the G1RLP275 is the 2-3/4 inch backset in passage/privacy. If the openings are mixed and you would rather not stock two backsets, the Lockey M230 is a mechanical keyless digital combination deadlocking spring latch lock with an adjustable backset, though that swaps the whole lock rather than just the latch. Backset on a fixed-backset latch cannot be shifted, so measure from the door edge to the center of the bore before ordering.

A deadlatch carries a small auxiliary plunger alongside the main latchbolt. When the door shuts, that plunger lands on the face of the strike and stays depressed, which mechanically blocks the latchbolt from being shimmed or carded back. A plain spring latch has no plunger and can be loided open. That is the reason a deadlatch gets specified on exterior and tenant entry doors. The Schlage 12-100 is the B250 Series latch itself, sold as a replacement part, not a complete lockset.

Just the latch. It is a B Series deadlatch sold as a replacement part, so the lock body and trim already on the door stay put and only the latch mechanism gets swapped. That is the order to place when a latch is sticking, worn, or damaged and the rest of the lock is sound.

Six finishes cover it: 605 bright brass, 609 antique brass, 612 satin bronze, 613 oil rubbed bronze, 622 matte black, and 626 satin chrome. Those numbers are the BHMA finish codes, so a 626 latch is the same 626 stamped on the rest of your Schlage trim. The faceplate is what shows once the door is hung, so match it to the strike and the lock trim on that opening.

Stainless steel through the latch, and it is built as a commercial part rather than a residential one, so it suits tenant entries, back-of-house doors and anything cycling all day. Stainless also resists corrosion, which is what matters on an exterior opening or anywhere salt air and washdown get at the door edge.

Mostly not. A replacement latch is built to the lock series it came out of. The Schlage 12-100 is a B250 Series latch, and Dexter's deadlatch is built for the C1000 Series. Even where backset and faceplate size line up, the latch still has to engage the lock body it was made for. Match the latch to the lock series on the door first, then confirm the backset.

Deltana's G1RLP238 and G1RLP275 are Grade 1 regular latches built for passage and privacy functions, at 2-3/8 and 2-3/4 inch backsets respectively. For a keyed entry opening at those same two backsets, the equivalents are the G1RLE238 and G1RLE275. Pick the backset off the bore already in the door, then pick the function off how the door is used.

A sidelite takes a purpose-built auxiliary latch, not a standard bored-door deadlatch. The Accentra YSSL10 security sidelite auxiliary latch is made for that opening, fits 1-3/4 inch doors, is fire rated, and comes with an ADA compliant thumbturn. Use the bored deadlatch on the active leaf and the sidelite latch on the fixed panel.

The Lockey M230 is a mechanical keyless combination lock with a deadlocking spring latch, no wiring and no keys, and it takes an adjustable backset with a 1-1/8 to 2 inch door thickness range. Codes get changed at the lock, which is why it shows up on shared entries, storage and common area doors. It replaces the whole lock though, not just the latch, so it is a different scope of work than dropping in a replacement deadlatch.

No. The 12-100 is a B250 Series deadlatch supplied as a Schlage replacement part, so it belongs in the Schlage B250 chassis it was built for. Dexter runs its own part for that job: the C1000-DL-630 is a deadlatch made for the Dexter C1000 series. A deadlatch is matched to the lock series it came out of, so order by the chassis on the door rather than by the fact that both parts are deadlatches.

Deltana runs two at that backset. The G1RLE238 is a regular latch with an entry function at 2-3/8 inch backset, and the G1RLP238 is the same 2-3/8 inch backset in a passage/privacy function. Both carry a Grade 1 rating. The distinction against the Schlage 12-100 is what you are buying: the 12-100 is a B250 Series replacement latch that goes back into an existing Schlage chassis, while the Deltana parts are latch units ordered by function first, so pick the Deltana by whether the opening is keyed entry or passage/privacy.

They are not interchangeable by function. The Schlage 12-100 is a B250 Series deadlatch, meaning it carries a deadlocking plunger alongside the latchbolt so the bolt is blocked from being pushed back once the door is closed against the strike. The Deltana G1RLP238 and G1RLP275 are listed with a passage/privacy function, and the G1RLE238 and G1RLE275 with an entry function. Order the latch that matches how the opening is used and how the lock it sits in is keyed, since a passage/privacy latch and a deadlatch behave differently at the strike.

No, they solve different problems despite both being latches. The YSSL10 is a security sidelite auxiliary latch with an ADA compliant thumbturn, fits a 1-3/4 inch door thickness, and is fire rated. It adds a latching point at a sidelite panel and is operated from the thumbturn. The Schlage 12-100 is a stainless steel B250 Series deadlatch supplied as a commercial replacement part, installed inside the lock chassis to restore latching on the door leaf itself. Buying the YSSL10 to fix a lock that will not latch leaves the original lock untouched.

The Lockey M230 is a mechanical keyless digital combination deadlocking spring latch lock with an adjustable backset, rated for door thicknesses from 1-1/8 to 2 inch. It is a complete lock, code operated, so the door no longer runs on a key. The Schlage 12-100 sits at the other end of the decision: a stainless steel B250 Series deadlatch supplied as a replacement part, which keeps the existing commercial lock, keyway and finish scheme intact and restores the latching. Go with the M230 when you want the keyed system off that door entirely, and the 12-100 when the lock is fine and only the latch is worn.
