Dormakaba 201144-744-01 – Frequently Asked Questions

1) Will the Dormakaba 201144-744-01 deadlatch fit my existing lock, or do I need to know the series first?
It is an OEM replacement deadlatch for Dormakaba 1000, L1000 and 5000 Series locksets only. Pull the existing latch and confirm the lock body is one of those three families before ordering. On any other lock brand or Dormakaba series, the latch case and lever engagement will not match.
2) What backset does this Dormakaba deadlatch require, and will it work in a 2-3/8 inch bored door?
The 201144-744-01 is a fixed 2-3/4 inch backset latch, not adjustable. If your door is prepped at 2-3/8 inches from the door edge to the center of the bore, this latch will not reach the strike properly, and you need a 2-3/8 inch backset version instead. Measure edge of door to center of the cylinder hole to confirm.
3) Can I use this latch on a 3-hour fire rated door?
Yes. The 201144-744-01 deadlatch is built for 3-hour fire rated door assemblies, which is why it matters that you replace a fire-rated latch with the same rated part rather than a generic latch. Swapping in an unrated latch on a rated opening compromises the assembly.
4) Is the Kwikset 83518 UL 3 hour latch a substitute for the Dormakaba 201144-744-01 deadlatch?
No. The Dormakaba 201144-744-01 is an OEM replacement deadlatch with a 2-3/4 in. backset and 3/4 in. throw made to fit Dormakaba 1000, L1000 and 5000 Series locksets, so the latch case and chassis interface are specific to those lock bodies. The Kwikset 83518 is an adjustable square drive UL 3 hour latch built for Kwikset lock bodies. Both are intended for use in fire-rated assemblies, but the Kwikset part will not seat correctly in a Dormakaba 1000, L1000 or 5000 Series lock. Stay with the Dormakaba part when the lock in the door is one of those series.
5) I need a 2-3/8 in. backset latch for a fire-rated door instead of the 2-3/4 in. Dormakaba - what are the options?
The Dormakaba 201144-744-01 is fixed at a 2-3/4 in. backset, so it will not serve a door bored at 2-3/8 in. For Kwikset lock bodies, the Kwikset 84290 is a square corner plainlatch with a 2-3/8 in. backset and a UL listing, and the Kwikset 83518 is an adjustable square drive UL 3 hour latch that can be set to the shorter backset. Both are Kwikset components and are not interchangeable with the Dormakaba 1000, L1000 or 5000 Series lock bodies, so confirm which manufacturer's lock is in the door before ordering.
6) Can I use a Deltana drive-in latch in place of the Dormakaba 201144-744-01 on a fire door?
The Deltana DLE23875 is a drive-in entry latch with an adjustable backset of 2-3/8 in. or 2-3/4 in. for doors 1-3/8 in. to 2 in. thick, and the Deltana DLP23875 is the same drive-in style in a passage/privacy function. They are drive-in bodies for residential-style tubular sets rather than OEM components for Dormakaba lock chassis, and neither is described for 3-hour fire-rated use. The Dormakaba 201144-744-01 is the commercial replacement deadlatch specified for 3-hour fire doors with 1000, L1000 and 5000 Series locks, so keep it on rated openings.
7) Is this a residential latch or a commercial one?
Commercial. The 201144-744-01 is a commercial-grade service part for Dormakaba lock families used in offices, healthcare, schools and municipal buildings, and it is sold as a maintenance replacement rather than as part of a complete lockset. Ordering it gets you the latch, not a lock body or trim.
8) I need a UL 3-hour latch but my lock is not Dormakaba. What else is there?
For a non-Dormakaba cylindrical lock, look at Kwikset's RCAL 3-hour UL latches instead: the 83518 is an adjustable square-drive version, and the 83521 is a plain latch for Kwikset BBL, KNL, CNL and PLL lock bodies. Those will not fit a Dormakaba 1000, L1000 or 5000 Series lock, and the Dormakaba latch will not fit theirs, so match the latch to the lock body you already have.
9) Is this a deadlatch or just a plain latch, and does it matter?
It is a deadlatch, meaning the latchbolt is deadlocked against being shimmed or carded when the door is closed. A plain latch, such as the Kwikset 84290 square corner plainlatch, has no auxiliary deadlocking plunger and is used where a lock body or separate deadbolt handles security. For an exterior or corridor opening on a rated assembly, keep the deadlatch.
10) What is the difference between a deadlatch like the Dormakaba 201144-744-01 and a plain latch such as the Kwikset 83521?
The Dormakaba 201144-744-01 is a deadlatch, meaning it carries a deadlocking plunger alongside the latchbolt that resists the bolt being pushed back once the door is closed, and it throws 3/4 in. at a 2-3/4 in. backset. The Kwikset 83521 is an RCAL plain latch with a UL 3 hour listing for Kwikset BBL, KNL, CNL and PLL lock bodies - a plain latch has the bolt without the deadlocking feature. Choose the deadlatch where the opening needs the bolt held against manipulation, and match the latch to the lock manufacturer in the door.
11) Would an Emtek EMPowered deadbolt latch work where the Dormakaba 201144-744-01 is called out?
No. The Emtek LC9-DBLTCH is a motorized deadbolt latch in the EMPowered series, a powered deadbolt component rather than a mechanical deadlatch for a lockset chassis. The Dormakaba 201144-744-01 is a mechanical OEM replacement deadlatch for Dormakaba 1000, L1000 and 5000 Series locks on 3-hour fire-rated doors. They serve different lock types and are not interchangeable.
12) What finish does the Dormakaba 201144-744-01 come in?
One finish only: 744, Dark Bronze with brass accents. Since a deadlatch face sits on the door edge and is visible when the door is open, it is worth matching this to the lever trim and hinges on the rest of the opening.
13) I only need a replacement faceplate, not the whole latch - is the Dormakaba 201144-744-01 the right part?
No. The Dormakaba 201144-744-01 is the complete deadlatch assembly with a 2-3/4 in. backset and 3/4 in. throw, finished in 744 Dark Bronze with brass accents. If the requirement is faceplate hardware only, the Emtek 83228 is a faceplate and screws set with square corners for a tubular pocket door privacy latch. That Emtek part is for pocket door privacy latches and does not fit a Dormakaba 1000, L1000 or 5000 Series lock.
