Sargent 10-3186 3 – Frequently Asked Questions

1) What Sargent locks does the 10-3186 latch work with?
It is a replacement component for Sargent 10-Line locksets. It is made to original Sargent tolerances, so it restores the lock at the part level rather than forcing a full lockset swap. It is not a universal tubular latch and should not be used to service other Sargent lines or other brands.
2) My door is prepped 2-3/4 inch backset. Is there an adjustable latch instead of the Sargent 10-3186?
The Sargent 10-3186 is built to a fixed 2-3/8 inch backset for Sargent 10-Line locksets, so it will not reach a 2-3/4 inch prep. For a bored door running standard tubular trim, 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 Deltana DLE23875 is the entry-function drive-in equivalent. Both Deltana latches suit doors 1-3/8 inch to 2 inch thick and are not replacements inside a Sargent 10-Line chassis.
3) Can a Kwikset 84290 plain latch be used in place of a Sargent 10-3186 guarded latch?
No. The Sargent 10-3186 is a guarded latch built as a replacement component for Sargent 10-Line locksets, with a 2-3/8 inch backset and a guarded latch design that resists latch manipulation. The Kwikset 84290 is a square corner plainlatch, also at a 2-3/8 inch backset, but it is a Kwikset residential-style part with no deadlatch guard and no 10-Line interface. The backset matches; the chassis interface and the guarded design do not. For a Sargent 10-Line lock, stay with the 10-3186.
4) What does a guarded latch do that a plain latch does not?
The guarded design on the 10-3186 puts a secondary guard alongside the latchbolt so the bolt resists being pushed back with a card or shim. On a plain latch there is nothing blocking that retraction. If the opening is an entry or tenant door where loiding is a concern, the guarded version is the one to service it with.
5) What finishes does the Sargent 10-3186 guarded latch come in?
Five: 03 Bright Brass clear coated, 04 Satin Brass clear coated, 09 Bright Bronze clear coated, 10 Satin Bronze clear coated, and 10B Dark Oxidized Satin Bronze oil rubbed. Match the code to the rest of the lockset so the exposed faceplate does not read off against the trim on the door.
6) I need a fire rated latch for a labeled door. Is this the right part?
If you need a documented UL fire rating on the latch itself, look at a latch that carries one, such as the Kwikset 83521 RCAL plain latch or the 84290 square corner plain latch at 2-3/8 inch backset, both listed UL. For a Sargent 10-Line lock, the 10-3186 is the correct replacement latch for that chassis and keeps the lock performing as originally built.
7) Can I replace just the latch instead of the whole Sargent lockset?
Yes, that is the point of the part. The 10-3186 is a component-level replacement, so a worn or damaged latch on a 10-Line lock can be swapped without pulling and re-keying a complete lockset. Confirm the existing prep is 2-3/8 inch backset and order the finish to match the lock already on the door.
8) I need a fire-rated latch for a residential entry door, not a Sargent 10-Line part. What should I look at?
The Sargent 10-3186 is a replacement latch for Sargent 10-Line commercial locksets and is sold as a genuine Sargent replacement part. If the opening is a residential-style door and you need a UL fire-rated latch, the Kwikset 83521 RCAL plain latch is listed as UL 3 hour and is intended for Kwikset BBL, KNL, CNL and PLL trim, and the Kwikset 83518 RCAL adjustable square drive latch is also UL 3 hour. Those are Kwikset-chassis parts and will not service a Sargent 10-Line lock.
9) We are moving a door to electronic access. Does the Sargent 10-3186 have a motorized equivalent?
The Sargent 10-3186 is a mechanical guarded latch that services a Sargent 10-Line lockset and has no electrified function of its own. If the goal is motorized operation on that opening, the Emtek LC9-DBLTCH is an EMPowered series motorized deadbolt latch in a deadbolt latch function. That is a separate deadbolt assembly on an Emtek platform, not a drop-in for a Sargent 10-Line chassis, so the mechanical lock would be replaced rather than serviced.
10) Is this Sargent latch suitable for a commercial building or is it residential grade?
It is a commercial part. Sargent lists the 10-3186 for commercial use, and it is the part locksmiths and facility staff use servicing 10-Line locks in offices, schools, healthcare, retail, government buildings, multi-tenant residential, and warehouses. For a residential tubular knob or lever, a drive-in latch like the Deltana DLP23875 is the more usual repair part.
11) Is the Emtek 83228 pocket door privacy faceplate an alternative to the Sargent 10-3186?
No. The Emtek 83228 is a faceplate and screws for a tubular pocket door privacy latch with square corners, a trim part for a sliding pocket door in a privacy/bed/bath function. The Sargent 10-3186 is the latch mechanism itself, a guarded latch with a 2-3/8 inch backset for a swinging door running a Sargent 10-Line lockset. Different door type and different part of the assembly.
