Dormakaba 91068 626 – Frequently Asked Questions

1) Which Dormakaba locks does the 91068 deadlatch fit?
The 91068 deadlatch is the factory replacement latch for Dormakaba 110, 140, and 144 series locks. It is a commercial part meant to restore original latch function in those lock bodies, so it is not a universal tubular latch for other brands' chassis.
2) What backsets does the Dormakaba 91068 latch come in?
Three backsets: 2-3/4 inch, 3-3/4 inch, and 5 inch. Measure from the door edge to the center of the lock bore on the door you are servicing and match it. The longer 3-3/4 and 5 inch backsets are what you need on wide stile or narrow aluminum-style applications where the cylinder sits farther in from the edge; 2-3/4 inch is the usual commercial bored-lock backset.
3) Will the 91068 latch drop into my existing square corner door prep?
Yes, if your prep is a square corner mortise for a 1-1/8 x 2-1/4 inch faceplate. The 91068 has a square corner front in that size and a 1 inch diameter latch body, which matches the standard 1 inch cross bore, so no rework of the edge mortise or the bore is needed. If your existing latch has a radius (round) corner front, the square plate will not sit in that pocket without re-chiseling the corners.
4) Is this a deadlatch or a plain latch, and does that matter for an exterior door?
It is a deadlatch, meaning it has an auxiliary anti-shim plunger alongside the main latchbolt that deadlocks the bolt once the door is closed against the frame stop. That is what you want on any keyed exterior or corridor opening, because it resists carding or prying the latch back. A plain latch, like the Kwikset 84290 square corner plainlatch, has no deadlocking plunger and belongs on passage and privacy functions only.
5) Is the Kwikset 84290 square corner plainlatch a substitute for a Dormakaba 91068 deadlatch?
No. The Dormakaba 91068 is a deadlatch built as a factory replacement for Dormakaba 110, 140, and 144 series lock bodies, with a 9/16 inch throw, a 1-1/8 inch by 2-1/4 inch square corner front, and a 1 inch diameter case, offered in 2-3/4 inch, 3-3/4 inch, and 5 inch backsets. The Kwikset 84290 is a square corner plainlatch at a 2-3/8 inch backset and is UL rated. Both share the square corner front shape, so the door and frame prep can look identical, but a plainlatch has no deadlocking plunger and the 84290 backset is shorter than any 91068 option. Use the 91068 when you are restoring latch function in a Dormakaba 110, 140, or 144 chassis.
6) What should I use on a residential entry door instead of the Dormakaba 91068 deadlatch?
The Dormakaba 91068 is a commercial replacement part matched to Dormakaba 110, 140, and 144 series lock bodies, so it is not a general-purpose latch for a residential knob or lever. For a residential entry door, the Deltana DLE23875 is a drive-in latch with an entry function that fits doors 1-3/8 inch to 2 inch thick. If the door only needs passage or privacy rather than a keyed entry function, the Deltana DLP23875 is a drive-in latch with an adjustable 2-3/8 inch or 2-3/4 inch backset for the same 1-3/8 inch to 2 inch door thickness range.
7) What finishes are available on the Dormakaba 91068 deadlatch faceplate?
Six: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 622 matte black, and 626 satin chrome. All six are offered on the 2-3/4 inch backset. The 3-3/4 inch and 5 inch backsets carry the same list except 605 bright brass. Match the faceplate to the lever or knob trim already on the door so the edge plate does not stand out.
8) I manage a building with Dormakaba 140 locks on several doors. Can I standardize on one latch part?
Yes, as long as the doors share a backset. The 91068 covers 110, 140, and 144 series locks, so one replacement latch part number services all three families across a facility. What you still have to verify door by door is the backset, since the part is ordered as 2-3/4, 3-3/4, or 5 inch, and the finish you want on the edge plate. Buying a small stock of the backset and finish combination you use most is the practical way to keep spares on the shelf.
9) I need a latch with an adjustable backset instead of ordering a fixed one. What are my options?
The Dormakaba 91068 is supplied in fixed backsets, ordered as 2-3/4 inch, 3-3/4 inch, or 5 inch to match the Dormakaba 110, 140, or 144 lock it is going into. If you want one part that covers two backsets, the Deltana DLP23875 is a drive-in latch with an adjustable 2-3/8 inch or 2-3/4 inch backset in a passage/privacy function, and the Kwikset 83518 is an adjustable square drive latch with a UL 3 hour rating. Neither is a Dormakaba chassis component, so for 110, 140, and 144 lock bodies the fixed 91068 is the matched part.
10) Is the Emtek 83228 faceplate an alternative to the Dormakaba 91068?
No. The Emtek 83228 is a faceplate and screws for a tubular pocket door privacy latch with square corners, so it replaces only the visible front plate. The Dormakaba 91068 is a complete deadlatch assembly with a 9/16 inch throw and a 1 inch diameter case, plus its own 1-1/8 inch by 2-1/4 inch square corner front. If the latch mechanism itself is worn or will not deadlock, you need the 91068; the 83228 covers a damaged or mismatched faceplate on an Emtek pocket door privacy latch.
11) Can the Emtek LC9-DBLTCH deadbolt latch replace the Dormakaba 91068?
No. The Emtek LC9-DBLTCH is a motorized deadbolt latch in the EMPowered series, meaning it throws a deadbolt under electric control and needs the power and control the EMPowered platform expects. The Dormakaba 91068 is a mechanical deadlatch that seats in a Dormakaba 110, 140, or 144 lock body and is driven by the lock's own retraction. Choose the LC9-DBLTCH for a motorized deadbolt opening and the 91068 for restoring mechanical latch function in the Dormakaba chassis.
12) I need a UL rated latch for a fire door opening. Does the Dormakaba 91068 cover that, or is there another part?
For a UL rated latch specifically, the Kwikset 83521 is a plain latch with a UL 3 hour rating for BBL, KNL, CNL, and PLL lock bodies, and the Kwikset 83518 is an adjustable square drive latch with the same UL 3 hour rating. The Dormakaba 91068 is a factory replacement deadlatch dimensioned to Dormakaba 110, 140, and 144 series lock bodies with a 9/16 inch throw and 1-1/8 inch by 2-1/4 inch square corner front, so on a Dormakaba opening it is the part that keeps the assembly to its original specification. Confirm the rating requirement against the lock body you are servicing before substituting a different manufacturer's latch.
13) Does the 91068 come with a strike plate or screws?
The 91068 is sold as the deadlatch itself, with its 1-1/8 x 2-1/4 inch square corner front. If you need a new strike for the frame, order that separately, and check the frame prep before you do, since a square corner latch front does not dictate the strike's corner style. If you are only replacing a worn faceplate on a different brand of latch, that is a separate part, for example the Emtek 83228 faceplate and screw set for square corner tubular privacy latches.
14) Is the Dormakaba 91068 latch rated for commercial traffic?
It is specified as a commercial door hardware part, supplied as the factory replacement latch for Dormakaba's 110, 140, and 144 commercial lock series. It is what you put back into a school, hospital, or office corridor lock, not a residential-grade drive-in latch.
