Dormakaba 55071-26D-01 – Frequently Asked Questions

1) Will the Dormakaba 55071 latch work in a door bored for a 2-3/8 inch backset?
No. The 55071 is a fixed 2-3/4 inch backset latch, so the cross bore has to be centered 2-3/4 inches from the door edge. On a 2-3/8 inch prep the latch tailpiece won't reach the lock hub. If your door is prepped at 2-3/8 inches, look at an adjustable-backset drive-in latch such as the Deltana DLP23875, which covers 2-3/8 or 2-3/4 inches for passage and privacy functions.
2) Do I have to replace the whole lockset, or can I just swap the latch?
Just the latch. The 55071 is sold as a replacement component for compatible Dormakaba mechanical lock sets, so when the latch is sticking or the spring has gone soft you pull the latch unit out of the edge bore and drop the new one in, keeping the existing lever, rose, and cylinder. That keeps the keying and the trim untouched, which matters if the opening is on a master key system.
3) Is there a latch equivalent to the Dormakaba 55071 that carries a UL fire rating?
The Dormakaba 55071 is described as a commercial-grade brass replacement latch for compatible Dormakaba mechanical lock sets. If the opening is a fire door and you need a UL-rated latch, the Kwikset 83521 RCAL plain latch is a UL 3 hour latch for BBL, KNL, CNL and PLL trim, and the Kwikset 83518 RCAL adjustable square drive latch is also UL 3 hour. Both are Kwikset parts, so they fit Kwikset lock chassis rather than Dormakaba.
4) Is the Dormakaba 55071 a deadbolt latch or a springlatch for a lever set?
It is a springlatch, a latch unit for a mechanical lock set rather than a deadbolt. Dormakaba sells it as a replacement part for their mechanical lock sets, so it goes into the existing cross bore behind the knob or lever and is retracted by the lock hub. If you need a motorized deadbolt latch instead, that is a different part entirely, like the Emtek LC9-DBLTCH EMPowered deadbolt latch.
5) Will the 55071 latch match the satin chrome hardware already on my other doors?
The 55071 comes in Satin Chrome, listed as 626 on the finish option and 26D in the model designation. 626 and 26D are the same brushed, low-gloss nickel-chrome tone used across most commercial lever and cylindrical lock lines, so the visible latch face will read the same as satin chrome trim on adjacent openings. Against bright chrome (625/26) it will look noticeably duller.
6) Can I use a drive-in latch like the Deltana DLE23875 in place of the Dormakaba 55071?
They install differently. The Dormakaba 55071 is a faceplate-style replacement latch with a 1/2 inch bolt and 2-3/4 inch backset intended for compatible Dormakaba mechanical lock sets. The Deltana DLE23875 is a drive-in latch with an entry function, made for doors 1-3/8 inch to 2 inch thick; a drive-in latch seats in the edge bore without a mortised faceplate, so the door edge prep is not the same. Use the Dormakaba part when you are restoring a Dormakaba lock set to factory fit.
7) Which latch parts look like substitutes for the Dormakaba 55071 but are not?
Two to rule out. The Emtek 83228 is a faceplate and screws set for a tubular pocket door privacy latch with square corners, so it is trim hardware for a pocket door application, not a latch bolt assembly for a swinging commercial door. The Emtek LC9-DBLTCH is a motorized deadbolt latch in the EMPowered series, a powered deadbolt component rather than a mechanical latch bolt. The Dormakaba 55071 is a mechanical brass latch with a 1/2 inch bolt and 2-3/4 inch backset.
8) Is a brass latch worth it over steel in a high-traffic building?
Brass is the body material here, and it is the reason this one holds up in corridors, restrooms, and exterior-adjacent openings: brass does not rust the way plated steel does when it sees humidity or cleaning chemicals. Dormakaba rates the part for commercial use, which is the duty level you want for schools, healthcare, and multi-tenant residential rather than a light residential latch.
9) What part number do I give my supplier to reorder this exact satin chrome latch?
Order Dormakaba 55071, model 55071-26D-01. The 26D in the middle is the satin chrome finish and it is the piece people drop when they reorder, which is how a bright chrome latch ends up in a satin chrome opening. The finish shows on the option list as 626 - Satin Chrome.
10) For a privacy or passage door, is the Dormakaba 55071 the right latch or is there a function-specific option?
The Dormakaba 55071 is sold as a replacement latch component, so the lock function comes from the Dormakaba chassis it serves rather than from the latch itself. If you are specifying a latch by function on a non-Dormakaba door, the Deltana DLP23875 is a passage/privacy drive-in latch and the Deltana DLE23875 is an entry-function drive-in latch, both for doors 1-3/8 inch to 2 inch thick.
