Dormakaba 91458 605 – Frequently Asked Questions

1) Which Dormakaba lock series does the 91450 deadlatch fit?
The Dormakaba 91450 deadlatch is the replacement latch for 210, 212, 225, 250, 253, 270 and 280 Series locks. It is the OEM part for those families, so it drops into the existing door edge prep on any of them without rework.
2) Do I need the 2-3/8 inch or 2-3/4 inch backset version of the 91450?
Measure from the door edge to the center of the lock bore. If that is 2-3/8 inches order the 2-3/8 inch latch (it carries a 1 inch pin depth); if it is 2-3/4 inches order that version, which uses a 1-1/8 inch pin depth. Those are the two backsets standard on cylindrical locks, and the wrong one will not reach the lock chassis.
3) Will the 91450 latch engage my existing strike?
The 91450 throws 1/2 inch, which is the normal projection for a cylindrical deadlatch, so it engages a standard commercial strike lip without moving the strike. If your old latch threw further than 1/2 inch, check strike depth before you close the door on it.
4) Is the 91450 front square corner or radius, and what size is the faceplate?
Square corner, 2-1/4 inches. That matters because the door edge mortise was routed either square or radius when the lock was first installed. If your existing prep has rounded corners, a square-corner front will leave gaps at the corners, and you want the radius version instead.
5) Can a Kwikset 84290 square corner plainlatch be used in place of a Dormakaba 91450 deadlatch?
They are different kinds of latch. The Dormakaba 91450 is a deadlatch built as an OEM replacement for Dormakaba 210, 212, 225, 250, 253, 270, and 280 Series locks, with a 1/2 inch throw and a 2-1/4 inch square corner front, offered in 2-3/8 inch and 2-3/4 inch backsets. The Kwikset 84290 is a square corner plainlatch in a 2-3/8 inch backset, meaning it has no deadlocking plunger and is intended for Kwikset cylindrical sets. If the existing lock body is a Dormakaba 210 through 280 Series, the 91450 is the part that restores original fit and function.
6) I need a latch with an adjustable backset instead of ordering a fixed one - what are my options?
The Dormakaba 91450 is ordered to a fixed backset, either 2-3/8 inch with a 1 inch pin depth or 2-3/4 inch with a 1-1/8 inch pin depth, so the backset has to be confirmed at the door before ordering. If you want one part that covers both dimensions, the Deltana DLP23875 is a drive-in latch with an adjustable backset of 2-3/8 inch or 2-3/4 inch in a passage/privacy function, and the Kwikset 83518 is an adjustable square drive latch with a UL 3 hour rating. Those are drive-in and Kwikset-pattern parts, so they do not restore a Dormakaba 210 through 280 Series lock body.
7) My opening is a fire door that needs a UL rated latch - is the 91450 the right part?
The Dormakaba 91450 is a commercial-grade OEM replacement deadlatch for Dormakaba 210, 212, 225, 250, 253, 270, and 280 Series locks, specified by its 1/2 inch throw and 2-1/4 inch square corner front. If the requirement on the drawing is a UL rated latch, the Kwikset 83518 adjustable square drive latch and the Kwikset 83521 plain latch both carry a UL 3 hour rating, and the 83521 is listed for Kwikset BBL, KNL, CNL and PLL sets. Those replace Kwikset lock bodies, so the lock chassis in the door decides which family you order from.
8) What finishes does the Dormakaba 91450 deadlatch come in to match the rest of my doors?
Five finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze and 630 satin stainless. All five are offered in both the 2-3/8 inch and 2-3/4 inch backsets, so you can standardize a building on one finish regardless of the bore spacing on each opening.
9) Is the 91450 a whole lockset or just the latch?
Latch only. The 91450 is the deadlatch assembly that sits in the door edge and engages the strike, not the chassis, trim or cylinder. Use it when the latch has worn or bound up and the rest of the 210 through 280 Series lock is still serviceable.
10) I need a square corner latch with a 2-3/8 inch backset but my lock is not a Dormakaba. What are my options?
For non-Dormakaba cylindrical locks, the Kwikset 84290 is a square corner plainlatch with a 2-3/8 inch backset, and the Kwikset 83521 RCAL plain latch covers Kwikset BBL, KNL, CNL and PLL chassis. Keep the 91450 for 210, 212, 225, 250, 253, 270 and 280 Series Dormakaba locks.
11) Is the Emtek 83228 square corner faceplate a substitute for the 91450?
No. The Emtek 83228 is a faceplate and screws only, for a tubular pocket door privacy latch in a privacy/bed/bath function - it supplies the visible plate, not the latching mechanism. The Dormakaba 91450 is a complete replacement deadlatch assembly with a 1/2 inch throw and a 2-1/4 inch square corner front for Dormakaba 210 through 280 Series locks. Matching square corners alone does not make the two interchangeable.
12) We are moving a few openings to electronic access - does the 91450 work with a motorized lock?
The Dormakaba 91450 is a mechanical replacement deadlatch for Dormakaba 210, 212, 225, 250, 253, 270, and 280 Series lock bodies and carries no electrified function. For a motorized latch, the Emtek LC9-DBLTCH is an EMPowered motorized deadbolt latch in a deadbolt latch function. That is a deadbolt rather than a deadlatch, so it addresses a different part of the opening than the 91450 does.
13) Is the Dormakaba 91450 suitable for high-traffic school and hospital doors?
It is built as a commercial component and is the factory latch for Dormakaba 210 through 280 Series locks used in offices, schools, healthcare, government buildings, retail, warehouses and multi-tenant residential. For an institutional maintenance shop, buying the OEM latch keeps the lock to its original design spec rather than mixing in aftermarket parts.
