Schlage 47273617 ALX Series Deadlatch, 2-3/4" Backset, 1-1/8" x 2-1/4" Square Corner

Yes. The 47273617 is the 2-3/4 inch backset version of the ALX Series deadlatch, so it drops into an opening prepped at 2-3/4 inches from the door edge to the center of the cross bore. If your door is bored at 2-3/8 inches, this is the wrong part and you need the shorter backset latch instead. The two backsets are not interchangeable and the latch cannot be adjusted between them.

The faceplate is 1-1/8 x 2-1/4 inches with square corners. If the door edge was previously routed for a radius corner faceplate, the square corner will not sit flush in that pocket, and you will need to square the corners of the mortise or order the radius version. A door edge already mortised square at 1-1/8 x 2-1/4 takes this latch with no rework.

A deadlatch has a small auxiliary plunger beside the main latchbolt. When the door closes, the plunger rides the strike and deadlocks the latchbolt so it cannot be pushed back with a card or shim. A plain spring latch has no plunger and can be loided. For any exterior or keyed entry opening, use the deadlatch. The 47273617 is the restoring deadlatch, which is what you want on a commercial entry.

It is an ALX Series latch, so it is built for Schlage ALX grade 2 cylindrical locks and mates to ALX lock trim. It is sold as a replacement part, so the usual job is swapping a worn or wrong-backset latch out of an ALX lever lock already hanging in the door rather than buying a whole new lockset.

Yes, and this is the detail that gets missed. The 47273617 uses a square cam, which is the tail shape that engages the retractor in the chassis. A latch with a round or other cam profile will physically enter the bore but will not retract when the lever is turned. Check the cam on the latch you are pulling out before you order.

For a non-Schlage chassis, the Deltana G1RLE275 is a Grade 1 regular latch in an entry function at the same 2-3/4 inch backset, and the G1RLP275 is the passage/privacy version at that backset. Pick by the function of the lock it goes into. Be aware those Deltana parts are regular latches, not deadlatches, so they have no auxiliary anti-loid plunger. If you want the deadlocking feature on a non-Schlage lock, the Dexter deadlatch for the C1000 Series is a Grade 2 deadlatch, but it is built for the Dexter C1000 chassis.

The Schlage 47273617 ALX deadlatch is a 2-3/4 inch backset part and will not reach a 2-3/8 inch bore. For a 2-3/8 inch prep, the Deltana G1RLE238 is a Grade 1 regular latch with an entry function, and the Deltana G1RLP238 is the Grade 1 regular latch in passage/privacy on the same 2-3/8 inch backset. Pick between them by whether the opening is keyed or a passage or privacy door.

The Deltana G1RLE275 is a Grade 1 regular latch with an entry function on a 2-3/4 inch backset, so it lands on the same backset as the Schlage 47273617 ALX deadlatch and covers a keyed entry opening. The Schlage 47273617 is a deadlatch built to work with ALX Series lock trim, so the Deltana is the choice when the trim on the door is not ALX and a Grade 1 entry latch is what the opening needs.

No. The Dexter C1000-DL-630 is a deadlatch built for the Dexter C1000 Series and carries a Grade 2 rating. The Schlage 47273617 is an ALX Series deadlatch intended to work with ALX lock trim. Both are deadlatches, but each is matched to its own lockset series, so the Dexter is the part for a C1000 chassis and not a replacement inside an ALX lock.

Commercial. The latch body is stainless steel, and it belongs to Schlage's ALX commercial lever line, so it is built for the cycle counts you see on office, school, and multi-family corridor doors rather than a house interior.

Nine finishes: 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. Only the faceplate shows once the door is closed, so match the finish code to the lever and strike you already have on the opening. On a fleet of doors, ordering the same finish code across the building keeps the edges consistent.

No. A cylindrical deadlatch is non-handed. The latchbolt is a bevel that flips, so the same part serves a left hand or right hand door. Rotate the bolt so the flat face points toward the stop before you slide it into the bore.

Just the latch. The 47273617 is the deadlatch assembly and faceplate only, a replacement part for an ALX lever lock. It does not include the lever trim, rose, cylinder, or strike. If you are replacing a failed latch, that is all you need; if you are building a new opening from nothing, you also need the ALX lockset and a strike.

For a sidelite that needs a fire rated auxiliary latch, the Accentra YSSL10 Security SideLite Auxiliary Latch carries a fire rating and an ADA compliant thumbturn, and is built for a 1-3/4 inch door thickness. The Schlage 47273617 is an ALX Series deadlatch for commercial lock trim in a standard door leaf, so the two address different openings rather than being interchangeable.

The Lockey M230 is a mechanical keyless digital combination lock with a deadlocking spring latch and an adjustable backset, fitting doors 1-1/8 inch to 2 inch thick. It replaces the whole lock rather than the latch alone. The Schlage 47273617 is a replacement deadlatch that goes into existing ALX lock trim, so it is the part when the lock stays and only the latch is being changed.

The Deltana G1RLE275 and G1RLP275 are Grade 1 regular latches on a 2-3/4 inch backset, offered in entry and passage/privacy functions respectively. The Schlage 47273617 is a restoring deadlatch with a 1-1/8 inch by 2-1/4 inch square corner faceplate and a stainless steel substrate, made to match ALX Series lock trim. A regular latch has no deadlocking plunger, so on a keyed exterior opening the deadlatch is the one that resists the latch being pushed back.
