Deltana DLP23875 Drive-In Latch: Adjustable Backset, Passage/Privacy
The Deltana DLP23875 is a drive-in tubular latch designed for interior residential doors where a clean, tool-minimal installation is required. The latch drives directly into a bored hole - no faceplate mortising - and the adjustable backset mechanism lets you set the throw at either 2-3/8" or 2-3/4" to match standard door prep without swapping parts. Available in seven finishes to coordinate with any interior hardware set.
The DLP23875 supports both passage and privacy functions. In passage mode the latch retracts freely from either side. Switched to privacy mode, the latch can be held from the inside - ideal for bathrooms, bedrooms, and home offices. No key cylinder is required or included; this is a non-keyed latch only.
Constructed from steel and zinc for durability in everyday residential use. The faceplate collar is finished to match the selected finish, so the installed result looks intentional rather than utilitarian.

Deltana DLP23875U15 – Frequently Asked Questions
1) What door thickness does the Deltana DLP23875 drive-in latch fit?
1-3/8 to 2 inches. That covers the common 1-3/8 inch interior residential door and runs up to 2 inches, so thicker solid-core and some panel doors are still in range. Below 1-3/8 or above 2 inches, this isn't the latch.
2) What is a drive-in latch and do I have to mortise the edge of the door for it?
No mortising. A drive-in latch has a round collar instead of a flat faceplate, so it taps straight into the 1 inch edge bore with no chisel work and no screws in the door edge. That is the whole point of the DLP23875: on a door that is already bored, it goes in with a hammer and a block of wood. If your existing latch has a rectangular faceplate let into the edge of the door, a drive-in will sit in the same bore but leave the old mortise pocket exposed, so on a replacement you either want a faceplate-style latch or plan to fill that recess.
3) Can I use the Deltana DLP23875 latch on a bathroom or bedroom door that needs to lock?
Yes, within limits. The DLP23875 handles both passage and privacy. In passage it retracts freely from either side; in privacy it holds from the inside, which is what a bath, bedroom or home office door needs. There's no cylinder and none can be added, so it will not do any keyed function. Privacy security comes from the knob or lever set you pair it with, not from the latch.
4) The door is prepped 2-3/8 inch backset only - is there a simpler latch than the Deltana DLP23875?
Yes. The Kwikset 84290 is a square corner plainlatch at a fixed 2-3/8 inch backset with a UL designation, so it does the same job on a 2-3/8 inch prep without an adjusting mechanism. The Deltana DLP23875 earns its keep when the prep is unknown or a mixed fleet of doors runs both 2-3/8 inch and 2-3/4 inch, since one part covers both. Note the difference in installed appearance as well: the 84290 is a square corner faceplate latch, while the DLP23875 drives directly into the bored hole with a finished collar and no faceplate mortise.
5) Is there an adjustable-backset latch other than the Deltana DLP23875 that works on a fire-rated opening?
For a fire-rated opening, look at the Kwikset 83518 RCAL Adjustable Square Drive UL 3 hour latch. Like the Deltana DLP23875, it adjusts rather than committing you to one backset, and it carries a UL 3 hour rating in its designation. The DLP23875 is a drive-in tubular latch adjustable to 2-3/8 inch or 2-3/4 inch, built for residential interior doors in steel and zinc, and is a passage/privacy non-keyed latch. If the door is a rated assembly, specify the Kwikset 83518; if it is an interior bedroom, bath, or office door, the Deltana is the drive-in tubular answer.
6) Is the Deltana DLP23875 latch handed, and do I need to know which way the door swings before ordering?
No handing to specify. It's a tubular latch with a beveled bolt, and finish is the only choice on the order: Brushed Nickel, Antique Nickel, Polished Chrome, Brushed Chrome, Oil Rubbed Bronze, Antique Brass, or PVD Polished Brass. Seven finishes, one part number, nothing else to call out.
7) Does the latch collar show once it's installed, and will it match my knobs?
The collar is visible on the edge of the door and it's finished to match the finish you order, so a DLP23875U15 in Brushed Nickel reads as part of a brushed nickel set rather than a bare steel ring. If you're matching Oil Rubbed Bronze trim, order DLP23875U10B; Antique Brass is DLP23875U5 and Brushed Chrome is DLP23875U26D.
8) I need a replacement latch for a pocket door privacy set, is this the right one?
No. The DLP23875 is a drive-in tubular latch for a bored swinging door, not pocket door hardware. For a tubular pocket door privacy latch, the Emtek 83228 faceplate and screws set is the square corner privacy part for that application.
9) Is a drive-in latch or a faceplate latch better for replacing a worn latch in an apartment turn?
Depends on what came out. If the old latch was drive-in, the DLP23875 drops into the same bore with no chisel and no screws, which is the fast turn. If the old latch had a rectangular faceplate mortised into the door edge, the recess stays visible behind a drive-in collar, and a square corner faceplate latch such as the Kwikset 84290 at 2-3/8 inch backset covers that prep instead. The DLP23875's advantage on a mixed portfolio is the adjustable backset: 2-3/8 or 2-3/4 off the same part.
10) What is the difference between the Deltana DLP23875 and the Emtek LC9-DBLTCH latch?
They serve opposite ends of the door. The Emtek LC9-DBLTCH is an EMPowered motorized deadbolt latch, so it is the deadbolt component of an electrified lock and expects power and a deadbolt prep. The Deltana DLP23875 is a non-keyed passage/privacy drive-in tubular latch in steel and zinc, entirely mechanical, with the backset adjustable between 2-3/8 inch and 2-3/4 inch. Use the LC9-DBLTCH where the opening needs a motorized deadbolt; use the DLP23875 for the knob or lever bore on an interior door that only needs to latch and hold privacy.
11) I am replacing latches across a building with knob and lever sets - which latch should I standardize on?
That depends on whether the doors are rated. The Kwikset 83521 is an RCAL plain latch with a UL 3 hour designation called out for BBL, KNL, CNL and PLL knob and lever sets, so it is the one to standardize on when those Kwikset trims are on the doors. The Deltana DLP23875 standardizes a different way: one part number covers both 2-3/8 inch and 2-3/4 inch preps on doors 1-3/8 inch to 2 inch thick and comes in seven finishes including Oil Rubbed Bronze, Brushed Nickel and Antique Brass, so a single latch matches varied interior hardware across a residential portfolio.
12) Does the Deltana DLP23875 come with a strike plate and screws?
The DLP23875 is the latch itself, a drive-in tubular unit with a finished collar and no faceplate screws, since nothing fastens to the door edge. It's non-keyed, so no cylinder is included and none is needed. Order the strike and the knob or lever trim separately to match your finish.
