Schlage Commercial ALX Series 2-3/4" Backset Restoring Spring Latch With 1" x 2-1/4" Square Corner Faceplate

No, and there is no adjusting it. Backset is the distance from the edge of the door to the center of the bore, and a 2-3/4 unit only seats correctly in a door prepped at 2-3/4. Those are the two backsets you run into: 2-3/4 on most commercial openings, 2-3/8 on residential and lighter interior doors. Measure from the door edge to the center of the hole the lock sits in before you order. If it comes back 2-3/8, you need the 2-3/8 backset version of the same Schlage latch, not this one.

That is exactly what the ALX Series spring latch is for. It is sold as a replacement part, the latch unit and its faceplate, and it works with the lock trim already on the door, so the lever, rose, and cylinder stay where they are. Nothing else comes in the box. Pull the existing latch first and confirm the backset and the faceplate corner style match before you order.

Both. The A Series latch adjusts for flat or beveled edge doors, so one part covers a square edge interior door and a beveled edge door hung in a metal frame. That matters if you are buying latches for a building where the doors are not all the same, since you are not sorting two part numbers at the door.

Not the same thing. A spring latch throws and retracts under spring pressure with nothing holding the bolt in the projected position. A deadlatch adds a small auxiliary plunger alongside the bolt that rides the strike face and blocks the bolt from being pushed back, which is what stops a card or shim from loiding the door open. On a keyed exterior or tenant entry opening, specify the deadlatch version. A plain spring latch is fine on interior passage, closet, and office doors where the concern is the door staying shut, not someone working the latch from outside.

Not without cutting. A square corner plate needs a square mortise. A prep routed for a radius corner plate leaves four rounded corners, and the square plate will sit proud until you chisel those corners out. It goes the other direction easily, a radius corner plate drops into a square mortise with a small gap at the corners. Look at the plate you are pulling off, and if the corners are rounded, order the radius corner version rather than reworking the door edge. 1 x 2-1/4 is the usual faceplate footprint on commercial cylindrical locks, so the mortise size itself is normally not the problem, only the corner shape.

Nine, so the faceplate can be matched to whatever trim is already hanging on each opening: 605 bright brass, 606 satin brass, 609 antique brass, 612 satin bronze, 613 oil rubbed bronze, 622 matte black, 625 bright chrome, 626 satin chrome, and 643E aged bronze. Once the door is closed the faceplate on the edge is the only part of the latch anyone sees, so on a mixed building match it to the lever rather than trying to standardize the latch finish across every door.

Commercial. The latch body is stainless steel, which is what you want on a door cycling all day and on anything facing weather, a pool corridor, a kitchen, or a coastal building where a plated steel part starts rusting at the faceplate. Schlage lists it as a certified Schlage part, so it is the service latch for the ALX line rather than a generic aftermarket replacement.

Deltana makes Grade 1 regular latches specified by function rather than as a service part for one lock line. The G1RLE275 is the entry function at a 2-3/4 backset and the G1RLP275 is the passage and privacy version at the same backset. Both also exist in 2-3/8 as the G1RLE238 and G1RLP238 if your door prep is the shorter backset. The difference in how you buy them is real: the Schlage ALX latch is chosen to match the lock already on the door, the Deltana latches are chosen by the function you need the door to have.

Different part entirely. A sidelite or inactive glass panel takes an auxiliary sidelite latch, not the latch out of a cylindrical lockset. The Accentra YSSL10 security sidelite auxiliary latch is built for that, comes with an ADA compliant thumbturn, is fire rated, and is listed for 1-3/4 inch thickness. Keep the ALX Series latch for the active leaf where the commercial lever lock is mounted.

No, the latch is a mechanical component and it does not change how the door is controlled. Keyless means changing the lock. The Lockey M230 is a mechanical keyless combination lock with a deadlocking spring latch and an adjustable backset, and it fits doors from 1-1/8 to 2 inches thick, so the same unit covers a thin interior door and a full 1-3/4 commercial leaf. Adjustable backset also means you are not matching an existing 2-3/8 or 2-3/4 prep. Being mechanical, there is no power or battery in the opening.

Deltana covers 2-3/8 inch in both functions: G1RLE238 is the Grade 1 regular latch for entry and G1RLP238 is the Grade 1 regular latch for passage/privacy, both at a 2-3/8 inch backset. Their deeper counterparts are G1RLE275 and G1RLP275, same Grade 1 rating and same entry-versus-passage/privacy split, at 2-3/4 inch. Where the opening is running Schlage lock trim, the ALX Series spring latch is the certified Schlage part for that door.

No. The M230 is a mechanical keyless digital combination deadlocking spring latch lock with an adjustable backset, meaning a complete keyless lockset rather than a latch on its own, and it is specified for doors 1-1/8 to 2 inches thick. The Schlage ALX Series spring latch is a stainless steel replacement part that goes in behind lock trim already on the door, so it restores the existing opening rather than converting it to keyless operation.

No, order those separately. The Dexter deadlatch is built for the C1000 series and is matched to that series, and a deadlatch is a different part from a spring latch. The Schlage ALX Series spring latch is a certified Schlage part that works with lock trim, so keeping each opening on its own series part number is what keeps the latch matched to the trim in the door.

Not with the Schlage ALX Series spring latch, which is adjustable for flat or beveled edge doors, so one part handles both edge conditions, and it comes in finishes including 626 Satin Chrome, 613 Oil Rubbed Bronze and 622 Matte Black to match the hardware already hanging on the doors. The Deltana Grade 1 regular latches divide up differently, by function and backset: G1RLE275 for entry or G1RLP275 for passage/privacy at 2-3/4 inch backset, which means a mixed building takes more than one Deltana part number.
