Accentra 280DN 626 – Frequently Asked Questions

1) Will the Accentra 280DN deadlatch fit a door prepped with a 2-3/8 inch backset?
No. The 280DN is a fixed 2-3/4 inch backset latch, so it will not line up in a door bored for 2-3/8 inches. If your opening is prepped at 2-3/8, you need a latch made for that backset, or an adjustable one such as the Deltana DLP23875, which covers both 2-3/8 and 2-3/4 inch backsets.
2) What lock does the Accentra 280DN deadlatch go into?
It is the replacement latch for Accentra 4300LN Series cylindrical locksets. It is built to that series' prep, so it drops into an existing 4300LN lock without swapping the whole lockset. Using it in another manufacturer's lock body is not something the part is made for.
3) What size is the faceplate on the Accentra 280DN latch, and will it cover my existing mortise in the door edge?
The face measures 2-1/4 x 1-1/8 inches. That is the standard small face used on the 4300LN Series, so if you are pulling a 4300LN latch out, the new one sits in the same edge mortise. If the door edge was routed for a larger face, you will see the old cutout around it.
4) What is the difference between a deadlatch and a plain latch, and which do I want on an exterior commercial door?
A deadlatch like the 280DN has a small deadlocking plunger riding alongside the main latchbolt. When the door closes, the plunger rests on the strike and blocks the latchbolt from being pushed back, which is what stops a card or shim attack. A plain latch, such as the Kwikset 84290 plain latch, has no plunger and is used on interior or non-security openings. For an exterior or tenant entry door, you want the deadlatch.
5) Can a Kwikset 84290 plain latch be used in place of an Accentra 280DN deadlatch?
No. The Accentra 280DN is a deadlatch built with a 2-3/4 inch backset and a 2-1/4 inch by 1-1/8 inch face for Accentra 4300LN Series locksets, and it carries the deadlocking plunger those locks depend on. The Kwikset 84290 is a square corner plainlatch with a 2-3/8 inch backset, so it is both a different backset and a plain latch rather than a deadlatch. Use the 280DN when you are restoring a 4300LN Series lock.
6) I need a latch for a residential door that takes either a 2-3/8 or 2-3/4 inch backset. Is the Accentra 280DN the right part?
The Accentra 280DN is a fixed 2-3/4 inch backset deadlatch matched to Accentra 4300LN Series commercial locksets, so it does not adjust. If you need one latch that covers both backsets, the Deltana DLP23875 is a drive-in latch with an adjustable 2-3/8 inch or 2-3/4 inch backset in a passage/privacy function, and the Deltana DLE23875 is the adjustable drive-in latch in an entry function; both list a 1-3/8 inch to 2 inch door thickness range.
7) Is the 280DN latch suitable for a high-traffic commercial opening or is it residential grade?
It is a commercial part. The 280DN is built for 4300LN Series locks in commercial service, the kind of use you see in offices, schools, healthcare, retail, and multi-tenant buildings. It is not a residential drive-in latch like the Deltana DLE23875, which is a tubular drive-in style for 1-3/8 to 2 inch doors.
8) Do I have to replace the whole lockset if the latch fails on a 4300LN lock?
No. The 280DN is sold as a standalone latch so you can service the opening without pulling and reordering a complete 4300LN lockset. Take off the trim, pull the old latch out of the edge mortise, and set the new one in the same 2-3/4 inch backset prep.
9) What should I use if the opening needs a fire-rated latch instead of the Accentra 280DN?
The Accentra 280DN is a replacement deadlatch specified for Accentra 4300LN Series locksets. If your requirement is a UL 3 hour rated latch, the Kwikset 83521 is an RCAL plain latch listed UL 3 hour for BBL, KNL, CNL and PLL locks, and the Kwikset 83518 is an RCAL adjustable square drive latch also listed UL 3 hour. Note those are Kwikset latches for Kwikset locks, not 4300LN components.
10) Is the Emtek LC9-DBLTCH an alternative to the Accentra 280DN?
They serve different openings. The Accentra 280DN is a mechanical deadlatch for Accentra 4300LN Series commercial locksets with a 2-3/4 inch backset. The Emtek LC9-DBLTCH is a motorized deadbolt latch in the EMPowered series, meaning it is a powered deadbolt component rather than a mechanical cylindrical lock latch. Pick the 280DN for a keyed-lever 4300LN retrofit and the LC9-DBLTCH only for an EMPowered motorized deadbolt.
11) Is the Accentra 280DN handed?
Cylindrical deadlatches of this style are non-handed in the sense that the latchbolt is reversible in the field by rotating it, so one part covers both left and right hand doors. Set the bevel so the flat side faces the direction the door swings closed before you mount the face.
12) I only need to replace a damaged latch faceplate, not the whole latch. Does the Accentra 280DN cover that?
The Accentra 280DN is the complete deadlatch assembly with a 2-1/4 inch by 1-1/8 inch face for 4300LN Series locksets, so it replaces the latch and its face together. If the job is a faceplate only on a tubular pocket door privacy latch, the Emtek 83228 is a faceplate and screws set with square corners for that privacy latch.
