Adams Rite 31-0275-04 – Frequently Asked Questions

1) What does the Adams Rite 31-0275-04 auxiliary bolt actually do in the lock?
The 31-0275-04 is the dead-latching auxiliary bolt. It rides against the strike when the door closes and blocks the main latch bolt from being pushed back, so nobody can loid or shim the latch open. If a door is latching but the latch can be pressed in by hand once closed, the auxiliary bolt is usually the failed piece.
2) Do I have to replace the whole Adams Rite lock, or can I just swap the auxiliary bolt?
You can service the lock instead of replacing it. The 31-0275-04 is sold as a drop-in replacement component for the Adams Rite mechanical lock assembly it belongs to, so a worn or broken auxiliary bolt can be changed out without pulling and replacing the complete unit. That's the point of ordering the part rather than a new lock.
3) I need a latch for a wood door with an adjustable backset instead of an Adams Rite part - what fits?
The Adams Rite 31-0275-04 is a commercial auxiliary bolt component sized to Adams Rite lock assemblies, not a standalone bored-door latch. For a wood door taking a standard drive-in latch, the Deltana DLP23875 offers an adjustable 2-3/8 inch or 2-3/4 inch backset in a passage/privacy function and fits doors 1-3/8 inch to 2 inch thick. If the opening is a keyed entry, the Deltana DLE23875 is the entry-function version with the same 1-3/8 inch to 2 inch door thickness range.
4) Can a Kwikset 84290 plain latch be used in place of the Adams Rite 31-0275-04 auxiliary bolt?
No. The Adams Rite 31-0275-04 is an auxiliary bolt replacement part for commercial mechanical lock assemblies, serving the dead-latching function that blocks retraction of the primary latch bolt. The Kwikset 84290 is a square corner plain latch with a 2-3/8 inch backset intended for a cylindrical bored lock. One is an internal component of an Adams Rite lock assembly, the other is a complete tubular latch unit, so they are not interchangeable.
5) Is the Adams Rite 31-0275-04 a genuine Adams Rite part or an aftermarket copy?
It's a factory Adams Rite component, made to the original spec and sold under the Adams Rite model number 31-0275-04. For a locksmith servicing an existing Adams Rite lock body, that matters more than it sounds: the auxiliary bolt has to match the original geometry to deadlatch correctly against the strike.
6) How do I make sure I'm ordering the right Adams Rite auxiliary bolt for my lock?
Order by the number stamped on the part or listed in the Adams Rite parts breakdown for your lock body. This one is 31-0275-04 and nothing else. Adams Rite auxiliary bolts are model-specific to the lock series they came out of, so matching the part number is how you confirm fit before it goes back in the door.
7) For a fire-rated opening, does the Adams Rite 31-0275-04 or a Kwikset RCAL latch apply?
The 31-0275-04 is the auxiliary bolt that restores dead-latching function inside an existing Adams Rite commercial lock assembly, and it is specified by that assembly rather than by an independent fire rating. Where the job calls for a bored-door latch carrying a UL 3 hour listing, the Kwikset 83518 is an adjustable square drive UL 3 hour latch and the Kwikset 83521 is the RCAL plain latch UL 3 hour version for BBL, KNL, CNL and PLL trim.
8) What is the difference between ordering the Adams Rite 31-0275-04 and an Emtek 83228 latch part?
Both are service components rather than complete locksets, but they serve different hardware. The Adams Rite 31-0275-04 is the auxiliary bolt inside a commercial Adams Rite mechanical lock assembly. The Emtek 83228 is a faceplate and screws for a tubular pocket door privacy latch, a residential-style trim part in Emtek's Parts series. Ordering one in place of the other will not restore the same function.
9) Is the Adams Rite 31-0275-04 worth stocking for a building maintenance shop?
If your openings run Adams Rite hardware, yes. The auxiliary bolt is a wear item on high-traffic aluminum storefront and commercial doors, and having one on the shelf turns a lock failure into a bench repair instead of a door out of service. It's the part facilities crews reach for in offices, retail, schools, healthcare, warehouses, multi-tenant residential, and municipal buildings.
10) If I want motorized or electronic latching instead of rebuilding the Adams Rite lock, what is the alternative?
The Adams Rite 31-0275-04 is a mechanical auxiliary bolt that returns an existing lock assembly to its original mechanical operation. If the goal is powered operation rather than a mechanical rebuild, the Emtek LC9-DBLTCH is a motorized deadbolt latch in the EMPowered series, which drives the bolt electrically instead of by key or thumbturn.
