Schlage Commercial D Series 14-042 - Deadlatch 2-3/4" Backset, 1-1/8" x 2-1/4" Face, 3/4" Throw, Anti-Friction, Square Corner

Both. The 14-042 latch adjusts between 2-3/8 and 2-3/4 inches, which are the two backsets you find on bored commercial and residential doors, so a single part covers either prep. Set it short for a 2-3/8 prep, long for the 2-3/4 prep more common on commercial openings. No separate part number and nothing extra to order for either setting.

That is the 14-042's face exactly: 1-1/8 x 2-1/4 inches, square corner. If the pocket routed into your door edge is square cut, the latch seats in it without any rework to the door. If the faceplate you are pulling out has radiused corners, the pocket is rounded at the ends and a square-corner face will not sit flush in it, so order the radius-corner version of the latch instead of trying to chisel the pocket square.

Latch only. The 14-042 is a replacement deadlatch for a Schlage Commercial D Series cylindrical lockset, so it covers a worn or failed latch behind a lever you are keeping. It does not include the chassis, lever trim, cylinder or strike. If what you actually want is a whole lock on that door, that is a different purchase, for example the Lockey M230 mechanical keyless combination lock, which uses a deadlocking spring latch with an adjustable backset and fits doors 1-1/8 to 2 inches thick.

A deadlatch carries a small auxiliary plunger alongside the main latchbolt. When the door shuts, the plunger rides up onto the strike plate and blocks the latchbolt from being pushed back, so the latch cannot be shimmed or carded open from the outside. On any exterior or tenant entry door, that is the latch you want. A plain spring latch without the plunger is fine on an interior passage door but has no such protection. The 14-042 is specified as a deadlatch, with a 3/4 inch bolt throw.

The bolt throws 3/4 inch past the faceplate, which is the normal projection for a bored-door deadlatch, so it engages the same strike a D Series lockset is already using. Watch the gap: the throw has to cover the space between door edge and frame plus the depth of the strike lip. On an opening where the door has settled and the gap has opened up, you are losing engagement from that 3/4 inch, and the fix is the frame or the strike, not a longer latch.

626 satin chrome is one of six finishes on the 14-042. The full run is 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright chrome and 626 satin chrome. The faceplate is visible on the door edge whenever the door stands open, so match the code to the lock trim rather than taking whatever is closest. Ordering one finish code across the whole property keeps the spare parts bin usable on any door in the building.

An anti-friction latch reduces the drag as the latchbolt wipes across the strike lip on closing, so the door latches positively instead of bouncing back. That is worth having on any door with a closer on it, and on doors fighting stack pressure or wind load in a stairwell or corridor. Construction is brass, and it is a certified Schlage part built for commercial duty rather than a residential-grade latch.

Two real differences. The Deltana G1RLE275 is a Grade 1 regular latch in entry function, bought at a fixed 2-3/4 inch backset, with the G1RLE238 as the separate 2-3/8 inch part number. The Schlage 14-042 is a deadlatch, so it carries the auxiliary deadlocking plunger a regular latch does not have, and the one part adjusts across 2-3/8 to 2-3/4. If the door you are working on is an interior passage or privacy opening rather than an entry, Deltana's G1RLP238 and G1RLP275 are the latches in that function.

Order the latch built for that chassis. Dexter lists its own deadlatch for the C1000 Series, and that is the part for a C1000 lock. The 14-042 is a Schlage D Series replacement latch. Matching the latch to the lock chassis is what keeps retraction geometry and the deadlocking plunger working the way the lockset expects, and it is the difference between a door that latches every time and a callback.

No, that is a different device. The 14-042 is the commercial deadlatch that goes into a Schlage D Series lock in the door leaf itself. For the sidelite, the Accentra YSSL10 is a security sidelite auxiliary latch with an ADA compliant thumbturn, carries a fire rating, and is listed for a 1-3/4 inch door thickness. Glass front work usually needs both: the deadlatch in the active leaf and the sidelite latch to secure the panel next to it.

Certified Schlage, sold as the factory replacement part under model number 14-042 for the Commercial D Series. When you are stocking a parts crib or writing a purchase order against a spec, that is the number to put on it, along with the finish code you need. Buying the OEM latch matters here because the deadlocking plunger and the anti-friction action have to work with the Schlage chassis, not just fit the hole in the door.

Both are deadlatches, but each is built for its own lock chassis. The Dexter DEXC1000-DL-630 is the deadlatch for Dexter's C1000 series, while the 14-042 is the Schlage D Series deadlatch with a 2-3/4 inch backset, a 1-1/8 inch by 2-1/4 inch square corner face and a 3/4 inch throw. Order the latch that matches the lock body already in the door, because the retractor and chassis engagement are specific to the series.

The Schlage 14-042 carries an adjustable 2-3/8 inch to 2-3/4 inch backset, so one part number covers both preps. The Deltana regular latches split by backset instead: the G1RLE238 is a 2-3/8 inch backset and the G1RLE275 is a 2-3/4 inch backset, both listed as Grade 1 with an entry function, so a mixed building means carrying two numbers. If your bore centers are measured door by door as you go, the adjustable latch removes the step of confirming backset before you order.

The 14-042 is a deadlatch, meaning it carries the auxiliary deadlocking plunger that keeps the main latchbolt from being pushed back once the door is closed against the strike. On an opening with no keyed function, Deltana lists regular latches in a passage/privacy function, the G1RLP238 at a 2-3/8 inch backset and the G1RLP275 at a 2-3/4 inch backset, both Grade 1. The deadlocking feature earns its keep on doors that are secured; a passage/privacy latch is the plainer mechanism for doors that only need to stay shut.

They solve different problems despite both using deadlocking spring latch language. The Lockey M230 is a complete mechanical keyless digital combination lock with an adjustable backset, sized for doors 1-1/8 inch to 2 inch thick, so it replaces the whole locking device and changes how the door is operated. The Schlage 14-042 is the latch alone, a brass replacement part that goes back into an existing D Series lock and leaves the trim, cylinder and keying exactly as they are.

Look at the latchbolt itself. The 14-042 is a deadlatch with an anti-friction latchbolt, a 3/4 inch throw and a 1-1/8 inch by 2-1/4 inch square corner face, and it is adjustable for flat or beveled edge doors. The Deltana G1RLE275 is a regular latch at the same 2-3/4 inch backset, listed as Grade 1 in an entry function, without the deadlocking plunger riding alongside the bolt. Backset alone will not distinguish them, so identify by the presence of the auxiliary plunger and the face dimensions.
