Deltana SLE23875 Square Latch Adj. Entry

Both. The SLE23875 square-corner latch covers a door thickness range of 1-3/8 inches to 2 inches, so it handles the thinner older interior doors as well as the 1-3/4 inch standard, and it still works on a heavier 2 inch entry slab. That range is wider than most tubular entry latches, which is what makes it usable across a mixed-vintage house or a building where door thicknesses were never standardized.

No measuring required to pick a part number. The SLE23875 is an adjustable-backset latch that sets to either 2-3/8 or 2-3/4 inches, which are the two backsets used on residential bored doors. You do need to know which one your door is bored for when you install it, since the latch has to be set to match the cross-bore centerline, but one part covers both.

Just the latch. The SLE23875 is the tubular latch mechanism that goes into the door edge and cross-bore; the knob or lever trim, the cylinder, and the strike are separate. It's an entry-function, single-cylinder keyed latch, meaning it is built to pair with keyed trim on the outside and a turn on the inside. If you are replacing a broken latch behind trim you want to keep, this is the part. If the trim is also going, you need a complete entry set.

It's a residential-rated part. Deltana lists the SLE23875 as residential, with a steel and zinc build, so it suits single-family, small multi-family units, and light-duty openings. For a commercial entry taking constant traffic, or for anything on a fire-rated opening, go with a commercial-grade latch instead. The Dexter Grade 1 deadlatch for the C1000 Series is a graded alternative, and the Accentra YSSL10 auxiliary latch is fire rated.

The Schlage 16-228 for the S200 and CS210 series is the nearest match in form: it is an adjustable 2-3/8 or 2-3/4 inch backset latch with a 1-1/8 by 2-1/4 inch face and square corners. The Deltana SLE23875 is likewise a square-face tubular latch with an adjustable 2-3/8 or 2-3/4 inch backset, set up for entry function with a single cylinder. If the existing mortise pocket in the door edge is square-cornered and you need the backset flexibility, the 16-228 covers the same opening geometry.

The Schlage 12-289 for the B500 series deadbolt has a 1 by 2-1/4 inch face with 1/4 inch round corners and an adjustable 2-3/8 or 2-3/4 inch backset. The Deltana SLE23875 is a square-face latch on the same adjustable 2-3/8 or 2-3/4 inch backset. Round-corner faces suit doors prepped with a routed pocket from a template; square corners suit a chiseled pocket. Match the corner to what is already cut in the door edge rather than re-prepping.

No. The Deltana SLE23875 is an entry-function latch, single cylinder, of the tubular type - it carries the spring latch that the knob or lever retracts. The Schlage 12-630 is a deadbolt latch for the B600, B700 and B800 series with a fixed 2-3/8 inch backset and a 1-1/8 by 2-1/4 inch square-corner face, and the 12-289 is a deadbolt latch for the B500 series. Those go into the deadbolt bore above the knob bore, not into the latch bore the SLE23875 serves. A door with both bores needs one of each.

The Deltana SLE23875 is a residential entry latch. Where the opening carries a fire rating, the Accentra YSSL10 auxiliary latch is fire rated and built for a 1-3/4 inch door, and it includes an ADA compliant thumbturn. For a rated commercial door the Dexter deadlatch for the C1000 series is a Grade 2 unit. Confirm the rating requirement on the door schedule before ordering, since a residential latch and a rated one are not interchangeable on that opening.

Different jobs on the same door. The SLE23875 is an entry-function spring latch, the one that retracts when you turn the knob or lever and keeps the door closed. The Schlage Commercial 12-289 is a B500 Series deadbolt latch, a bolt you throw deliberately with a key or thumbturn; it has no knob action at all. A typical entry door runs both. If you're replacing the part that operates with the handle, that's the Deltana. If you're replacing the part above it that only moves with the key, you want the deadbolt latch.

The SLE23875 is Deltana's square-corner adjustable latch, set to 2-3/8 or 2-3/4 inch backset. On the commercial side, the Schlage 16-228 for the S200 and CS210 Series is adjustable to the same two backsets with a 1-1/8 by 2-1/4 inch square-corner face, and the Schlage 16-480 deadlatch for the S200 Series is adjustable the same way with a 1 by 2-1/4 inch square-corner face. Square corner matters because a radius-corner faceplate will not sit right in a square-routed door edge without recutting the mortise.

Not on its own. The SLE23875 is a keyed entry latch in a single-cylinder configuration, but the latch itself carries no cylinder. Keying lives in the exterior trim's cylinder, so keying alike across a set of doors is decided by the cylinders you order with the trim, not by this part. Buying the same latch across several doors does standardize the backset and the door prep, which is the useful part for a property manager holding a mixed stock of doors from 1-3/8 up to 2 inches thick.

No. The SLE23875 bottoms out at 1-3/8 inches. For a thinner slab, a gate panel, or a non-standard door down to 1-1/8 inches, the Lockey M230 covers 1-1/8 to 2 inches and also has an adjustable backset, though it is a keyless mechanical combination lock rather than a keyed latch, so it changes how the door is operated as well as what fits.

The Schlage 16-480 for the S200 series is a deadlatch with an adjustable 2-3/8 or 2-3/4 inch backset and a 1 by 2-1/4 inch square-corner face. It matches the Deltana SLE23875 on backset adjustment and on the square corner, and differs in that it is a deadlatching unit with a narrower 1 inch face. A deadlatch adds the auxiliary plunger that blocks the latch from being carded when the door is closed, which is the usual choice on an exterior entry.

The Lockey M230 is a mechanical keyless digital combination deadlocking spring latch lock with an adjustable backset, and it fits doors from 1-1/8 to 2 inches thick. The Deltana SLE23875 is keyed with a single cylinder and fits 1-3/8 to 2 inch doors. On a rental turn or a shared entry where handing out keys is the problem, the M230 changes the access method entirely - no cylinder, no key, a combination at the door - while the SLE23875 keeps the opening on the same key system as the rest of the building.

Door thickness is the deciding spec. The Deltana SLE23875 covers 1-3/8 to 2 inch doors on an adjustable 2-3/8 or 2-3/4 inch backset. The Lockey M230 reaches down to 1-1/8 inch and also runs to 2 inches, so it spans thinner interior slabs the SLE23875 does not. The Accentra YSSL10 is specific to 1-3/4 inch doors. If the fleet is a mix of 1-3/8 and 1-3/4 inch doors, the SLE23875 covers both from one part number.

Eight finishes: PVD Polished Brass, Polished Brass, Antique Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome, and Brushed Chrome. Only the faceplate on the door edge shows once installed, so matching matters most if the door stands open a lot or the edge is visible from a hallway. PVD Polished Brass is the one to pick over standard Polished Brass on an exterior door, since the PVD coating holds up to weather and handling better than lacquered brass.
