Schlage ALX Series Deadlatch, 2-3/4" Backset, 1" x 2-1/4" Round Corner

ALX Series only. It is a Schlage replacement latch built for the ALX lever chassis, and it will not interchange with other Schlage lock lines. Before ordering, check the backset already bored in the door: ALX locks are prepped at either 2-3/8 or 2-3/4 inches, and the latch has to match what is in the door. If it does not, the latch tail will not line up with the chassis when you draw the lock together.

Yes, the ALX deadlatch is sold on its own as a Schlage replacement part, so a seized or dragging latch gets swapped without touching the lever, chassis, or cylinder. Pull the lock, back off the faceplate screws, slide the old latch out of the cross bore, and reverse. The latch is not handed, so the same part serves a left- or right-hand door. Latch body is stainless steel, which is what you want in an opening that sees weather or a wet mop line.

It is the anti-loiding feature. The small plunger riding alongside the main spring latch bolt is held depressed by the strike face when the door closes, and in that position it blocks the latch bolt from being pushed back with a shim or a card. If the plunger is bent, missing, or dropping into the strike hole instead of landing on the strike face, the opening is no more secure than a plain spring latch. That failure is one of the most common reasons to change the latch rather than the whole ALX lock.

Satin chrome (626) is one of eight finishes the ALX deadlatch is offered in, along with bright chrome (625), bright brass (605), satin brass (606), antique brass (609), satin bronze (612), oil rubbed bronze (613), and aged bronze (643E). Order the latch in the same finish code as the levers already on the doors. Only the faceplate shows once the door is hung, but across a corridor of openings a mismatched faceplate is exactly what a tenant or an inspector picks up on.

Commercial. Schlage builds this ALX latch as a commercial part and makes it in stainless steel, which is what keeps it from corroding on an exterior opening or a corridor door that gets mopped, and what lets it take all-day cycling. For an MRO or facilities buyer standardizing on ALX levers, it is a sensible spare to hold on the shelf in the building's finish.

No. The Schlage part is an ALX Series latch and it will not interchange with a Dexter C1000 chassis. Dexter makes its own deadlatch for the C1000 Series, and that is the part to order for that lock. Latches are not cross-brand items even when the faceplate looks the same, because the tail slot and the way the latch engages the retractor differ by manufacturer.

Deltana's G1RLE275 is a Grade 1 regular latch for entry function at a 2-3/4 inch backset, and the G1RLE238 is the same latch at 2-3/8 inch. If the door is a passage or privacy opening rather than keyed entry, the matching parts are the G1RLP275 and G1RLP238. Function matters as much as backset: an entry latch and a passage latch are not interchangeable inside the chassis. The Schlage ALX latch is not an option on any of those doors, since it only fits ALX Series locks.

No. It is a chassis latch for an ALX lever lock, not a sidelite part, and a narrow sidelite panel takes its own prep. For that application the Accentra YSSL10 security sidelite auxiliary latch is the right type of part: it is fire rated, made for 1-3/4 inch doors, and supplied with an ADA compliant thumbturn.

If the aim is to get off keys entirely rather than fix the existing lever, the Lockey M230 is a mechanical keyless combination lock with a deadlocking spring latch and an adjustable backset, and it takes doors from 1-1/8 to 2 inches thick. The adjustable backset is the practical part: it picks up the existing cross bore whether the door was prepped at 2-3/8 or 2-3/4. The Schlage ALX deadlatch is a repair part, so it only makes sense where the ALX lever is staying on the door.

The Deltana G1RLE275 is a Grade 1 regular latch in an entry function cut for a 2-3/4 inch backset, so it lands on the same bore-to-edge dimension as the Schlage ALX deadlatch. The difference is what each one is built around: the Schlage part is a replacement latch matched to the ALX series, with a stainless steel body, so it goes back into an ALX lockset and keeps the assembly original to the chassis. The Deltana is sold as a standalone Grade 1 entry latch rather than a series-matched replacement. If an ALX lock is staying on the door and only the latch is being swapped, the ALX deadlatch is the like-for-like part; if you are latching an opening that is not carrying an ALX chassis, the G1RLE275 covers the same 2-3/4 inch backset.

Yes. The Deltana G1RLP275 is a Grade 1 regular latch in a passage/privacy function at a 2-3/4 inch backset, and the G1RLP238 is the same latch at a 2-3/8 inch backset. Their entry-function counterparts are the G1RLE275 and G1RLE238, both Grade 1 at the matching backsets. The Schlage part is an ALX Series spring latch supplied as a replacement component for ALX locksets, so it is specified by the lock it serves rather than chosen by function on its own. On an interior door where the lockset is already in place and only the latch has failed, match the latch to that lockset; on a bare opening being specified from scratch, the Deltana passage/privacy latches address the no-lock condition directly.

Treat them as series-specific parts rather than generic latches. The Dexter deadlatch is built for the Dexter C1000 series, and the Schlage deadlatch is built for the ALX series as a replacement component. Two deadlatches can share a backset and still differ in the tailpiece window, the retractor geometry, and the way the case indexes into the chassis, which is what decides whether the lock actually cycles once it is together. For a maintenance stock, the practical move is to stock by the lock line on your doors: the ALX deadlatch for ALX openings, the C1000 deadlatch for Dexter C1000 openings.

No, they solve different problems. The Lockey M230 is a complete mechanical keyless digital combination lock with a deadlocking spring latch and an adjustable backset, sized for doors 1-1/8 to 2 inches thick. Buying it means replacing the whole lock and moving the opening to pushbutton code entry, with the adjustable backset covering either standard bore dimension. The Schlage ALX deadlatch is the latch alone, a replacement part for ALX series locksets, so it suits the case where the ALX lock stays on the door and the latch is what needs renewing. Choose the M230 when you are changing how the door is accessed; choose the ALX deadlatch when the access method is staying as it is.

That is a dedicated part rather than a bored-door latch. The Accentra YSSL10 is a security sidelite auxiliary latch with an ADA compliant thumbturn, sized for 1-3/4 inch doors and carrying a fire rating, which is what a sidelite or narrow stile position generally calls for: its own thumbturn on the inside and a latch case suited to that leaf. The Schlage ALX deadlatch is a stainless steel replacement latch for ALX series locksets on commercial openings, so it belongs in the lock chassis on the main door leaf. On a pair where the main door carries an ALX lock and the sidelite needs to secure independently, those are two separate parts, not one substituting for the other.
