Sargent 10-3430 32D – Frequently Asked Questions

1) Will the Sargent 10-3430 latch fit a door prepped for a 2-3/8 inch backset?
No. The Sargent 10-3430 is a 2-3/4 inch backset latch, so the cross-bore in the door has to sit 2-3/4 inches from the door edge. On a 2-3/8 inch prep the spindle and latch tail will not line up and you would be re-boring the door. For a 2-3/8 inch prep in a residential-grade tubular application, Kwikset's 84290 square corner plain latch is built to that backset.
2) Does the Sargent 10-3430 have a square corner or radius faceplate?
Square corner. That matters because the mortise pocket in the door edge has to match: a square corner faceplate drops into a square-routed pocket, and a door already routed with a radius corner will need the pocket squared off or the corners will not seat flush.
3) Can I use the Sargent 10-3430 guarded latch in a non-electrified 10 Line lockset?
It is built as the guarded latch for the electrified functions in the Sargent 10X Line. If you are repairing a powered or access-controlled 10X Line lock, this is the matching part. For a straight mechanical 10 Line lock, order the latch Sargent specifies for that function rather than the electrified one.
4) Is the Kwikset 84290 square corner plainlatch a substitute for the Sargent 10-3430?
No. The Kwikset 84290 is a square corner plainlatch built to a 2-3/8 inch backset, while the Sargent 10-3430 is a 10X Line guarded latch cut for a 2-3/4 inch backset. The corner geometry matches but the backset does not, so the 84290 will not land on a door bored for 2-3/4 inch. The 10-3430 is also a commercial replacement part for Sargent 10X Line electrified functions, where the guarded latch resists shimming - a plain latch does not do that job.
5) I need a latch that works at either 2-3/8 or 2-3/4 inch backset - what should I look at instead of the Sargent 10-3430?
The Sargent 10-3430 is fixed at a 2-3/4 inch backset, so it only fits that prep. If you need one part to cover both preps on residential-weight doors, the Deltana DLP23875 is a drive-in latch with an adjustable 2-3/8 inch or 2-3/4 inch backset for passage and privacy functions, rated for 1-3/8 inch to 2 inch door thickness. Note that it is a drive-in latch for passage/privacy, not a guarded latch for electrified commercial locksets, so it is a different application rather than a direct swap.
6) What does a guarded latch actually do on a commercial door?
The guard is the secondary plunger alongside the latchbolt. When the door closes, the guard rides the strike and deadlocks the bolt so it cannot be shimmed or carded from the outside. On an access-controlled opening that is the difference between a door that reads secure to the system and one that can be pushed open with a shim.
7) Which finishes does the Sargent 10-3430 latch come in, and do they need to match the lockset?
Twelve finishes: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B oil rubbed dark oxidized satin bronze, 10BE, 10BL, 20D dark statuary bronze lacquered, 32 bright stainless, 32D satin stainless, plus BSP black suede and WSP white suede powder coat. Only the faceplate shows once the latch is installed, so order the code matching the rest of your Sargent hardware on that opening. Property managers standardizing a building usually stay on 32D or 10B.
8) Is the Sargent 10-3430 a residential replacement latch?
No, it is a commercial part, sold as a genuine Sargent replacement component for 10X Line locksets in high-traffic openings. For residential tubular doors the Deltana DLE23875 drive-in entry latch or DLP23875 passage/privacy latch cover 1-3/8 to 2 inch doors and are the right class of part there.
9) I am replacing a failed latch on an electrified Sargent lock. Do I need to change the strike too?
Not if the opening is otherwise unchanged. The 10-3430 is a drop-in replacement at the same 2-3/4 inch backset with a square corner faceplate, so an existing Sargent 10X Line prep and strike stay as they are. Swap the strike only if the old one is worn, or if you are moving from a different backset or corner style, since either changes where the bolt lands.
10) What is the difference between the Deltana DLE23875 and the Sargent 10-3430 latch?
The Deltana DLE23875 is a drive-in adjustable latch for entry function on doors 1-3/8 inch to 2 inch thick - a residential-style latch that drives into the bore without a faceplate mortise. The Sargent 10-3430 is a square corner faceplate guarded latch at 2-3/4 inch backset, built as a genuine replacement component for Sargent 10X Line electrified locksets in commercial service. Choose the Deltana for entry-function drive-in preps and the Sargent when you are rebuilding a 10X Line lock.
11) Can I use the Emtek LC9-DBLTCH motorized deadbolt latch on an electrified opening instead of the Sargent 10-3430?
They do different jobs. The Emtek LC9-DBLTCH is an EMPowered series motorized deadbolt latch - the latch itself is driven by the motor and throws a deadbolt. The Sargent 10-3430 is a mechanical guarded latch that serves the electrified functions of a Sargent 10X Line lockset, where the electrification is in the lock body rather than the latch. If you are servicing a Sargent 10X Line lock, the 10-3430 is the matching part; the Emtek is for its own EMPowered deadbolt platform.
12) I only need a square corner faceplate, not a whole latch - is there a cheaper option than the Sargent 10-3430?
If the latch body is sound and only the faceplate is damaged, the Emtek 83228 is a faceplate and screws kit with square corners for tubular pocket door privacy latches. It is a faceplate-only part for that Emtek privacy latch, not a Sargent component, so it will not serve a Sargent 10X Line lock. For a 10X Line electrified opening the 10-3430 supplies the complete guarded latch with the square corner faceplate as one assembly.
13) For a fire rated opening, is the Kwikset 83521 an alternative to the Sargent 10-3430?
The Kwikset 83521 is a RCAL plain latch carrying a UL 3 hour rating, used with Kwikset BBL, KNL, CNL and PLL locks, and the Kwikset 83518 is the adjustable square drive version of that UL 3 hour latch. Both are tied to Kwikset lock bodies. The Sargent 10-3430 is a commercial guarded latch made for Sargent 10X Line electrified functions at a 2-3/4 inch backset, so on a Sargent opening the 10-3430 is the part that preserves the original lock assembly.
14) Does buying the Sargent 10-3430 latch get me any of the electrified parts of the lock?
No. It is the latch assembly only, the mechanical part that sits in the door edge. Solenoids, wiring harnesses, power transfers and the trim stay with the existing 10X Line lock. If the fault is that the lock will not release on signal rather than that the bolt is binding or the guard is failing, the problem is upstream of this part.
15) We are standardizing bronze and stainless hardware across a building - which latch gives us finish options to match?
The Sargent 10-3430 guarded latch is offered across a broad finish range including 10 satin bronze clear coated, 10B dark oxidized satin bronze oil rubbed, 20D dark statuary bronze lacquered, 03 bright brass, 04 satin brass, 32 bright stainless steel, 32D satin stainless steel, plus BSP black suede and WSP white suede powder coat. The comparable drive-in and plain latches such as the Deltana DLP23875 and Kwikset 83521 are described by function and backset rather than a matching architectural finish range, so the Sargent is the one that lets you carry a single finish schedule through the openings.
