Dormakaba 55071-05-01 – Frequently Asked Questions

1) Is this Dormakaba latch a universal replacement, or only for Dormakaba locks?
It is a replacement component for compatible Dormakaba mechanical lock assemblies, not a universal drive-in latch. If you are servicing another brand's lockset, match the latch to that lock instead of substituting this one.
2) What is a comparable latch if the door is prepped for a 2-3/8 inch backset instead of 2-3/4 inch?
The Dormakaba 55071-05-01 is built to a fixed 2-3/4 inch backset, so it will not reach a bore centered at 2-3/8 inches. For that prep, the Kwikset 84290 is a square corner plainlatch made specifically for a 2-3/8 inch backset. Another route is an adjustable-backset latch such as the Deltana DLP23875, which sets to either 2-3/8 inch or 2-3/4 inch on the same part.
3) The opening is a fire-rated door. Is the Dormakaba 55071-05-01 latch the right choice there?
The Dormakaba 55071-05-01 is a commercial brass replacement latch for compatible Dormakaba mechanical lock assemblies, sold on its fit and finish rather than on a fire listing. Where the door assembly requires a latch carrying a fire rating, the Kwikset 83521 RCAL plain latch and the Kwikset 83518 RCAL adjustable square drive latch are both described as UL 3 hour parts. Match the latch to the lockset it serves, since the Kwikset RCAL latches are intended for Kwikset cylindrical bodies.
4) What size latch face does the Dormakaba 55071-05-01 have?
It is a 1/2 inch latch face. That matters because the mortise cut in the door edge has to match: a 1/2 inch face will sit loose in a prep routed for a wider faceplate, and a wider face will not drop into a 1/2 inch cut without rework.
5) Does this Dormakaba latch carry a fire rating for a labeled door?
Treat the 55071-05-01 as a standard commercial service latch and specify a fire-labeled latch where the opening is rated. Kwikset's RCAL latches are the UL 3 hour options here: the 83521 plain latch for BBL, KNL, CNL and PLL locksets, the 84290 square corner plainlatch at a 2-3/8 inch backset, and the 83518 adjustable square drive latch.
6) Can I use the 55071-05-01 to convert a lock to privacy or entry function?
No. It is a latch replacement, not a function change. The latch restores latching in an existing Dormakaba mechanical lock and the function stays whatever the lock chassis and trim provide. If you are changing function, order the latch that matches the target lockset instead, for example a Deltana DLP23875 in Passage/Privacy or DLE23875 in Entry when you are working with a compatible tubular prep.
7) I manage several buildings and do not want to stock two backsets. Is there a single latch that covers both door preps?
Yes. The Dormakaba 55071-05-01 is a single-backset part at 2-3/4 inches, so covering both preps with it means stocking a second number. The Deltana DLP23875 is an adjustable-backset drive-in latch that sets to 2-3/8 inch or 2-3/4 inch and is a passage/privacy function; the Deltana DLE23875 is the entry-function drive-in equivalent. Both Deltana latches list a door thickness range of 1-3/8 inch to 2 inch, so confirm your leaves fall inside that before standardizing.
8) Will a drive-in latch like the Deltana DLE23875 substitute for the Dormakaba 55071-05-01?
Not interchangeably. The Dormakaba 55071-05-01 is a faceplate-style latch with a 1/2 inch latch face sized to Dormakaba mechanical lock preparations. The Deltana DLE23875 is a drive-in latch, meaning it seats into the bore without a mortised faceplate, and it is an entry-function part for doors 1-3/8 inch to 2 inch thick. If the door edge is already mortised for a faceplate, the drive-in body leaves that cutout exposed.
9) Which of these parts look like latch replacements but will not work as one?
Two in the same neighborhood are not substitutes for the Dormakaba 55071-05-01 brass latch. The Emtek 83228 is a faceplate and screws only, for a tubular pocket door privacy latch with square corners, so it supplies trim rather than a latch mechanism. The Emtek LC9-DBLTCH is a motorized deadbolt latch in the EMPowered series, an electrified deadbolt component rather than a mechanical latch bolt for a knob or lever lock.
10) Is the 55071-05-01 rated for commercial traffic or is it a residential part?
Commercial. Dormakaba lists the 55071-05-01 as commercial door hardware, and it is the latch used to restore latching function in commercial mechanical lock assemblies in offices, schools, healthcare, retail, warehouse, multi-tenant residential, and government buildings.
11) Will the Antique Brass finish on this latch be visible once the door is closed?
Only the faceplate on the door edge shows, and on the 55071-05-01 that face is finished in Antique Brass to sit alongside traditional-finish levers, knobs and hinges. On painted or dark hollow metal frames the edge plate reads as a visible trim piece, so matching it to the rest of the opening is worth doing.
12) Why choose a brass latch over a steel one for a commercial door?
Brass is the material used here for smooth latch operation and corrosion resistance over a long service life, and it carries the Antique Brass finish on the exposed faceplate without plating over steel. On high-cycle openings the value of a brass latch is consistent retraction, so the lever does not start dragging as the latch wears.
13) For a square-corner faceplate at 2-3/8 inch backset, what is the closest alternative to the Dormakaba 55071-05-01?
The Kwikset 84290 is a square corner plainlatch with a 2-3/8 inch backset. It differs from the Dormakaba 55071-05-01 in backset, since the Dormakaba part is fixed at 2-3/4 inches, and the Dormakaba latch is a brass part offered in Antique Brass to coordinate with existing trim. Verify the faceplate corner style and size against what is mortised in the door edge before ordering either.
