Dormakaba 201144-26D-01 – Frequently Asked Questions

1) Will the Dormakaba 201144 deadlatch fit my existing 2-3/4 inch backset door prep?
Yes. The 201144 is built to a 2-3/4 inch backset, which is the standard commercial prep, so it drops into an opening already bored for a 2-3/4 backset lockset without redrilling. It is not an adjustable latch, so if your door is bored at 2-3/8 inches this is the wrong part.
2) Which Dormakaba locksets does the 201144 latch work with?
It is the OEM replacement latch for Dormakaba 1000, L1000 and 5000 Series locksets. If your cylindrical lock is from one of those three families, the 201144 is the direct latch swap. It is not intended for other manufacturers' chassis.
3) Can I use this latch on a 3-hour fire rated door?
Yes, the 201144 is rated for 3-hour fire door applications. That matters on stairwell, corridor and shaft openings where the whole assembly has to hold its rating, and swapping in a non-rated latch would void it.
4) I need a 2-3/8 in. backset latch instead of 2-3/4 in. - what are my options?
The Dormakaba 201144 is built to a 2-3/4 in. backset only, so it will not serve a 2-3/8 in. bore. For a 2-3/8 in. backset the Kwikset 84290 is a square corner plainlatch at 2-3/8 in. backset with a UL rating, and the Deltana DLP23875 drive-in latch is adjustable to either 2-3/8 in. or 2-3/4 in. Note that neither is a Dormakaba part, so confirm the lock chassis they are going into.
5) Can I use the Kwikset 83521 plain latch on a 3-hour fire door instead of the Dormakaba 201144?
Both are rated for 3 hour fire door use, but they serve different lock families. The Kwikset 83521 is an RCAL plain latch for Kwikset BBL, KNL, CNL, and PLL locks. The Dormakaba 201144 is the OEM 2-3/4 in. backset deadlatch for Dormakaba 1000, L1000, and 5000 Series locksets. A plain latch also lacks the deadlocking plunger a deadlatch provides, so it is not a like-for-like swap on a Dormakaba commercial lockset.
6) Will a 3/4 inch throw latch engage my existing strike?
The 201144 throws 3/4 inch, which is the deeper commercial throw rather than the 1/2 inch typical of residential tubular latches. Against a standard commercial frame strike with a full lip cutout it engages fine; if your frame has a shallow dust box you may need to confirm depth before swapping.
7) Is this a deadlatch or a plain latch, and does it matter?
It is a deadlatch. The auxiliary deadlatching plunger rides the strike lip and blocks the latchbolt from being carded or shimmed back. On an exterior or tenant entry door you want the deadlatch version; a plain latch has no anti-shim function.
8) I need a 3-hour rated latch but my lock isn't a Dormakaba. What else is available?
The 201144 only suits Dormakaba 1000, L1000 and 5000 Series chassis. For Kwikset locks, ZenSupply carries the Kwikset 83521 RCAL plain latch, UL 3 hour, for BBL, KNL, CNL and PLL locks, and the Kwikset 83518 RCAL adjustable square drive UL 3 hour latch if you need to cover both common backsets.
9) Is the Emtek LC9-DBLTCH deadbolt latch the same kind of part as the Dormakaba 201144?
No. The Emtek LC9-DBLTCH is a motorized deadbolt latch in the EMPowered line, meaning it is an electrified deadbolt component. The Dormakaba 201144 is a mechanical deadlatch with a 3/4 in. throw and 2-3/4 in. backset that replaces the latch in Dormakaba 1000, L1000, and 5000 Series cylindrical locksets on 3-hour fire doors. They are different functions and different door preps.
10) What finish does the Dormakaba 201144 latch come in and will it match my other hardware?
Satin chrome only, listed as 626 satin chrome (26D on the model designation 201144-26D-01). That is the standard commercial finish, so the exposed faceplate will match 626/26D levers and strikes already on the openings.
