Dormakaba 91076 626 – Frequently Asked Questions

1) What backset does the Dormakaba 91076 deadlatch have, and will it drop into my existing door prep?
It is a fixed 2-3/4 inch backset latch with a 1-1/8 x 2-1/4 inch square corner front. If the door is bored on the other common commercial backset, 2-3/8 inches, this latch will not line up and you need the 2-3/8 version instead. The front is square corner, so a door edge routed for a radius-corner faceplate would need re-routing or a filler.
2) What is the difference between the Dormakaba 91076 deadlatch and the Kwikset 84290 square corner plainlatch?
Both use a square corner front, but they are prepped for different backsets and different lock families. The Dormakaba 91076 is a 2-3/4 inch backset deadlatch with a 3/4 inch throw and a 1-1/8 inch by 2-1/4 inch front, built for Dormakaba 100 Series non-restoring locks. The Kwikset 84290 is a square corner plainlatch on a 2-3/8 inch backset. A plainlatch is a plain spring latch without the deadlocking plunger the 91076 carries, so on a 2-3/4 inch bored door running a 100 Series lock the 91076 is the matching part.
3) What finishes does the Dormakaba 91076 deadlatch come in?
Five: 606 Satin Brass, 612 Satin Bronze, 613 Oil Rubbed Bronze, 622 Matte Black, and 626 Satin Chrome. Pick the one matching the lock trim already on the door so the exposed faceplate does not read as a mismatch across a run of openings.
4) Will a 3/4 inch throw deadlatch engage my existing strike?
The bolt projects 3/4 inch, which is standard for a commercial deadlatch, so it engages a normal ANSI strike pocket without changing the frame. The bolt cylinder is 1 inch in diameter, which is what the 100 Series latch bore expects.
5) Is the 91076 a deadbolt or a deadlatch?
It is a deadlatch: a spring latch with a deadlocking plunger that blocks the bolt from being carded back when the door is closed. It retracts with the lever or knob and is not a separate keyed deadbolt. For a powered deadbolt latch instead, the Emtek LC9-DBLTCH EMPowered motorized deadbolt latch is a different animal entirely.
6) Do I have to replace the whole 100 Series lock if the latch is worn out?
No. The 91076 is a factory replacement latch component, so a worn or sticking latch on a 100 Series non-restoring lock can be swapped without pulling the lock body or re-prepping the door, provided your existing prep is 2-3/4 inch backset with a square corner front.
7) Is the Emtek 83228 faceplate a substitute for the Dormakaba 91076?
No. The Emtek 83228 is a faceplate and screws only, for a tubular pocket door privacy latch with square corners - there is no latch mechanism in it. The Dormakaba 91076 is the complete deadlatch assembly, including the 1 inch diameter bolt cylinder and 3/4 inch throw bolt, with the 1-1/8 inch by 2-1/4 inch square corner front attached. Square corners on both is where the similarity ends.
8) Is this latch rated for high-traffic commercial openings?
Yes, the 91076 is a commercial part, not residential trim, and the 1 inch bolt cylinder is sized for commercial cycling. It is the parts-level replacement used in offices, schools, healthcare, retail, warehouses, multi-tenant residential, and government buildings.
9) If I want an electrified latch instead of the Dormakaba 91076, what is the option?
The Emtek LC9-DBLTCH is an EMPowered series motorized deadbolt latch, meaning the bolt is driven by a motor rather than by a key or thumbturn. The Dormakaba 91076 is a purely mechanical deadlatch with a 3/4 inch throw, retracted by the trim on a Dormakaba 100 Series non-restoring lock. They serve different openings: the LC9-DBLTCH belongs to an access-controlled deadbolt platform, while the 91076 restores an existing mechanical 100 Series lock.
