Dormakaba 55071-03-01 – Frequently Asked Questions

1) What size latch bolt does the Dormakaba 55071-03-01 use?
It's a 1/2 inch latch bolt. That matters when you're matching the existing strike in the frame, since a 1/2 inch throw latch needs the strike lip and pocket positioned for that engagement depth. If the door currently latches correctly with a 1/2 inch bolt, this replacement will engage the same strike without reworking the frame.
2) I need a latch that works at either 2-3/8 or 2-3/4 inch backset - what should I use instead of the Dormakaba 55071-03-01?
The Dormakaba 55071-03-01 is fixed at a 2-3/4 inch backset. If the door prep is uncertain or you are stocking for both preps, the Deltana DLP23875 is a drive-in latch with an adjustable backset of 2-3/8 inch or 2-3/4 inch for passage and privacy functions, and the Deltana DLE23875 is the adjustable drive-in latch for entry function. Both Deltana latches cover door thicknesses of 1-3/8 inch to 2 inch. Note that the Deltana units are drive-in style rather than a faceplate latch matched to a Dormakaba chassis.
3) What is the difference between the Dormakaba 55071-03-01 latch and the Kwikset 84290 plainlatch?
The Dormakaba 55071-03-01 is a 1/2 inch brass latch with a 2-3/4 inch backset in Bright Brass, sold as a genuine replacement part for compatible Dormakaba mechanical lock systems. The Kwikset 84290 is a square corner plainlatch with a 2-3/8 inch backset. So the two differ both in the backset dimension and in the lock line they belong to - the 55071-03-01 is matched to Dormakaba lock chassis, while the 84290 is a Kwikset component.
4) Is this a genuine Dormakaba replacement latch or an aftermarket part?
It's a genuine Dormakaba component, catalogued as model 55071-03-01 and intended as a replacement latch for compatible Dormakaba mechanical lock systems. For a locksmith or property maintenance team keeping an existing Dormakaba lockset in service, that's the point: the retractor engagement and prep match what came out of the door.
5) What finish is the Dormakaba 55071-03-01 latch, and will it match my other hardware?
One finish only: 605 Bright Brass, on a solid brass latch body. It coordinates with polished brass levers, roses and strikes. If the rest of the opening is satin chrome or oil-rubbed bronze, the latch face will stand out where it shows on the door edge, so a different finish code is the better call there.
6) Does this Dormakaba part include a strike plate or screws?
The 55071-03-01 is the latch itself, a 1/2 inch brass latch with a 2-3/4 inch backset. Strikes and separate faceplate/screw kits are ordered as their own parts. As an example of how those are catalogued elsewhere, Emtek sells the 83228 as a faceplate and screws kit for its tubular pocket door privacy latch. If you're replacing a worn latch in an otherwise good Dormakaba lockset, the existing strike normally stays in the frame.
7) Is the Dormakaba 55071-03-01 a fire rated latch, or do I need something else for a rated opening?
The Dormakaba 55071-03-01 is described as a commercial-grade brass replacement latch with a 1/2 inch latch bolt and 2-3/4 inch backset for compatible Dormakaba mechanical locks. If your specification calls out a UL 3 hour latch, Kwikset publishes that rating on two components: the 83521 RCAL plain latch UL 3 hour for BBL, KNL, CNL and PLL trims, and the 83518 RCAL adjustable square drive UL 3 hour latch. Those are Kwikset parts and are matched to Kwikset lock bodies, not to a Dormakaba chassis.
8) Can I use the Emtek 83228 faceplate or the Emtek LC9-DBLTCH in place of the Dormakaba 55071-03-01?
No - neither is a substitute. The Dormakaba 55071-03-01 is a complete 1/2 inch brass latch unit with a 2-3/4 inch backset for compatible Dormakaba mechanical locks. The Emtek 83228 is only a faceplate and screws for a tubular pocket door privacy latch with square corners, so it replaces trim rather than the latch itself. The Emtek LC9-DBLTCH is a motorized deadbolt latch in Emtek's EMPowered line, an electrified deadbolt component rather than a mechanical latch bolt.
9) Is this latch rated for commercial traffic or is it a residential part?
Commercial. The 55071-03-01 is specified for commercial door hardware use, and brass construction gives it corrosion resistance for long service in offices, schools, healthcare, retail, warehouses, multi-tenant residential and government buildings.
10) I need a privacy or passage latch, not a Dormakaba lock part - what are my options?
The Dormakaba 55071-03-01 is a replacement latch for compatible Dormakaba mechanical lock systems and is supplied in Bright Brass with a 2-3/4 inch backset. If you are building a standalone privacy or passage opening, the Deltana DLP23875 is a drive-in latch listed for passage/privacy function, and the Deltana DLE23875 covers entry function. For a tubular pocket door privacy latch, the Emtek 83228 supplies the square corner faceplate and screws for that assembly.
