Sargent 16-0321 – Frequently Asked Questions

1) What does the Sargent 16-0321 plastic filler actually do?
It is a filler piece that lets a standard bolt sit correctly in a standard 161 door preparation. Without it the bolt assembly does not fill the prep properly and the alignment is off. It is a Sargent 470 Series replacement part, so you are restoring a factory fit rather than shimming something together on site.
2) Will the Sargent 16-0321 work with a lock that is not a Sargent 470 Series?
Plan on 470 Series only. The filler is engineered for the Sargent 470 Series family and for a standard 161 door prep with a standard bolt. Cross-brand or cross-series fit isn't something to assume on a part this dimensionally specific.
3) For a residential door with a drive-in latch bore, is the Sargent 16-0321 the right part?
The Sargent 16-0321 is a commercial replacement part built for the Sargent 470 Series and a standard 161 door prep. A drive-in bore on a residential door is a different preparation entirely - the Deltana DLE23875 drive-in latch is an entry function for doors 1-3/8 inch to 2 inch thick, and the Deltana DLP23875 is the passage/privacy drive-in latch with adjustable 2-3/8 inch or 2-3/4 inch backset for the same thickness range. Those suit a drive-in bore; the 16-0321 does not.
4) Can a Kwikset 84290 plainlatch be used instead of the Sargent 16-0321 plastic filler?
No. The Sargent 16-0321 is a plastic filler that lets a standard bolt sit correctly in a standard 161 door prep - it is a filler piece, not a latch. The Kwikset 84290 is a square corner plainlatch with a 2-3/8 inch backset, so it replaces the latch itself rather than filling out the prep around one. If the bolt is fine and only the prep fitment is loose, the 16-0321 is the part that addresses it.
5) If the latch itself is worn out rather than the prep fitment, what should be ordered instead of the Sargent 16-0321?
The Sargent 16-0321 is a no-finish plastic filler for the 470 Series that only corrects bolt fitment in a 161 door prep. If the latch body is the problem, a replacement latch is the right part: the Kwikset 83521 RCAL plain latch is UL 3 hour rated for BBL, KNL, CNL and PLL, and the Kwikset 83518 RCAL is an adjustable square drive UL 3 hour latch. Those change the latching mechanism; the 16-0321 does not.
6) Do I need to order the 16-0321 filler in a finish to match my lock?
No finish is required. The filler is a plastic component that needs no finishing step, so there is nothing to match to the lockset trim and nothing extra to buy alongside it.
7) Is the 16-0321 filler a commercial part or will it work on a residential door?
It is built for commercial mechanical lock applications, specifically Sargent 470 Series hardware in a 161 prep. Typical use is office buildings, schools, healthcare, retail, industrial facilities, multi-tenant residential and government buildings. If you are working on a residential tubular latch, this is not the part.
8) Is a 161 door prep the same thing as the standard cylindrical lock prep in my doors?
Yes, 161 is the common cylindrical prep designation used across commercial doors, which is why the 16-0321 is a useful part to keep on the shelf for a building standardized on Sargent 470 Series locks. The filler makes a standard bolt fill that prep correctly.
9) Is there a fire rated latch option if my opening is a labeled door?
The 16-0321 filler is not a fire rated assembly on its own, it is a fit component for a 161 prep. If a fire rating is what you need on the latch itself, Kwikset lists UL 3 hour latches: the 83518 adjustable square drive and the 83521 plain latch for BBL, KNL, CNL and PLL trims.
10) Is the Emtek 83228 faceplate a substitute for the Sargent 16-0321?
They solve different problems. The Emtek 83228 is a faceplate and screws for a tubular pocket door privacy latch with square corners - a visible trim plate for a pocket door application. The Sargent 16-0321 is a plastic filler that sits in a standard 161 door prep so a standard bolt fits, and it requires no finish because it is not a trim piece.
11) Can the Sargent 16-0321 be used on an electrified or motorized deadbolt opening?
The Sargent 16-0321 is a mechanical lock part - a plastic filler for a standard bolt in a 161 door prep within the 470 Series. For a motorized deadbolt, the Emtek LC9-DBLTCH is an EMPowered motorized deadbolt latch, which is a powered latch assembly rather than a prep filler. The two are not interchangeable.
