Dormakaba 201144-03-01 – Frequently Asked Questions

1) Will the Dormakaba 201144-03-01 deadlatch fit my existing door prep?
It's built to a 2-3/4 inch backset, which is the standard commercial bore-to-edge dimension, so it drops into an existing Dormakaba 1000, L1000, or 5000 Series prep without redrilling. If your doors are prepped at 2-3/8 inches (common on residential-weight openings), this latch is the wrong backset.
2) Can I use this latch on a 3-hour fire rated door?
Yes. The 201144-03-01 deadlatch is rated for use on 3-hour fire doors, so it can go back into a fire-rated assembly without breaking the rating of the opening. That is the reason to specify this part number rather than a generic replacement latch, which will not carry a fire rating.
3) Which Dormakaba locksets does the 201144-03-01 deadlatch replace the latch in?
It is the replacement deadlatch for Dormakaba 1000, L1000, and 5000 Series locksets. If the cylindrical lever or knob set on your door is from one of those three families, this restores latch function without changing the lock body or trim.
4) Will a 3/4 inch throw latch engage my existing strike?
The deadlatch projects 3/4 inch, which is the throw the original Dormakaba latch in the 1000, L1000, and 5000 Series provides. Since it matches the original, the existing strike and frame prep will accept it as is, with no strike change and no shimming.
5) I need a UL 3-hour latch but the lock is not Dormakaba. What else is there?
The 201144-03-01 is prepped for Dormakaba 1000, L1000, and 5000 Series bodies only. On Kwikset cylindrical sets, the Kwikset 83521 RCAL plain latch is a UL 3-hour latch for BBL, KNL, CNL, and PLL trims, and the Kwikset 83518 RCAL adjustable square drive latch is the UL 3-hour adjustable version. Match the latch to the lock brand; latch tailpiece and case geometry are not interchangeable across manufacturers.
6) Do I need anything else to swap the latch, or is the 201144-03-01 all I need?
It's a drop-in replacement latch for the 1000, L1000, and 5000 Series, so the lock chassis, trim, cylinder, and strike stay in place. If the strike or faceplate in the frame is damaged or the wrong finish, that gets ordered separately; this part number covers the latch itself.
7) Will the Emtek 83228 faceplate or the Emtek LC9-DBLTCH work with a Dormakaba 1000 Series lockset?
No. The Dormakaba 201144-03-01 is a complete replacement deadlatch with a 2-3/4 inch backset and 3/4 inch throw for Dormakaba 1000, L1000 and 5000 Series locksets. The Emtek 83228 is a faceplate and screws only, for a tubular pocket door privacy latch with square corners, so it is trim rather than a latch body. The Emtek LC9-DBLTCH is a motorized deadbolt latch in the EMPowered line, which is a powered deadbolt component, not a mechanical deadlatch.
8) What finish does this Dormakaba replacement deadlatch come in?
Bright Brass, BHMA finish code 605. Most of the latch body is concealed in the door, so the finish only shows on the faceplate at the edge, which will read consistently against 605 trim on the same opening.
9) For a fire door, which latch adjusts to more than one backset?
The Dormakaba 201144-03-01 is a fixed 2-3/4 inch backset deadlatch with a 3/4 inch throw, rated for 3-hour fire doors and matched to Dormakaba 1000, L1000 and 5000 Series locksets. If you need one part to cover two bore dimensions, the Kwikset 83518 is a RCAL adjustable square drive latch with a UL 3 hour rating, though it is a Kwikset component and will not fit a Dormakaba chassis.
