Arrow 116 26D – Frequently Asked Questions

1) Which backset do I order for the Arrow 115 deadlatch, 2-3/8 or 2-3/4?
The Arrow 115 deadlatch comes in both 2-3/8 inch and 2-3/4 inch backsets, so you have to match the existing door prep. Measure from the door edge to the center of the bore hole: if it lands at 2-3/8 inches you need the 2-3/8 latch, at 2-3/4 you need the other. There is no adjustable version of the 115, so the backset you pick is fixed.
2) Will the Arrow 115 latch work in a non-Arrow lockset?
No. The 115 is built as a replacement latch for Arrow MK Series locksets and is sized to that lock's prep and hub. If the lock body in your door is another brand, source the latch for that brand instead of dropping this one in.
3) What does drive-in mean on this latch, and do I need a faceplate?
Drive-in means the latch housing is driven straight into the 1-inch cross bore in the door edge, with no mortised faceplate and no screws through a plate. That is why it installs fast and why it needs an unmortised, round-edge prep. If your door edge is mortised flat for a rectangular faceplate, a drive-in latch is the wrong choice for that opening.
4) My lock is residential, not Arrow MK. Is there an adjustable drive-in latch instead?
For a residential or light-duty tubular lock, the Deltana DLE23875 drive-in latch is adjustable between the two common backsets and is listed for 1-3/8 to 2 inch doors in an entry function. Deltana also makes the DLP23875 in passage/privacy if the door does not lock with a key. The Arrow 115 is a commercial part tied to Arrow MK Series lock bodies and is not a general-purpose substitute.
5) Is there a drive-in latch with an adjustable backset instead of ordering a fixed 2-3/8 inch or 2-3/4 inch deadlatch?
The Arrow 115 deadlatch is ordered to a fixed backset, either 2-3/8 inch or 2-3/4 inch, both in 626 satin chrome. If one part that covers both dimensions is preferred, 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 a drive-in latch in an entry function. Note that the Arrow 115 is engineered specifically for Arrow MK Series locksets, so the Deltana parts are alternatives for openings where an MK Series lockset is not the host.
6) Which drive-in latch should I use on a keyed entry door rather than a bed or bath door?
Function is the dividing line. The Arrow 115 is a deadlatch, giving positive deadlatching action to resist latch manipulation, which is the behavior wanted on a secured commercial opening. Among drive-in alternatives, the Deltana DLE23875 is listed in an entry function while the Deltana DLP23875 is passage/privacy, and the Emtek 83228 faceplate and screws serve a tubular pocket door privacy latch in a privacy/bed/bath function. Passage and privacy parts do not deadlatch.
7) What is a deadlatch doing that a plain latch does not?
A deadlatch carries a small auxiliary plunger beside the main latchbolt. When the door closes, the plunger hits the strike and locks the latchbolt against being pushed back, so the door cannot be shimmed or carded open. A plain latch, like the Kwikset 84290 plainlatch, has no such plunger and gives no anti-manipulation protection. On an exterior or tenant entry door you want the deadlatch.
8) I have a fire-rated door. Can I use the Arrow 115 deadlatch on it?
Don't assume it from the deadlatch function. Fire door openings need latching hardware carrying the listing called out on the door label, and that listing has to be confirmed for the specific part. If your job requires a labeled latch on the drawing, verify the listing for the exact Arrow MK part number your lock takes before you install.
9) Can I use the Arrow 115 to standardize latch replacements across a building?
Yes, if the building runs Arrow MK Series locksets. It is the factory replacement latch for that series, and stocking it in both 2-3/8 and 2-3/4 inch backsets in 626 covers most MK openings in an office, school, healthcare, retail, or multi-tenant building. Walk the doors first and record which backset each prep uses, since the two are not interchangeable.
10) I need a latch with a UL fire rating for a rated opening. Does the Arrow 115 cover that, or is there another part?
The Arrow 115 is a genuine Arrow replacement deadlatch for MK Series commercial locksets, specified by backset and finish. Where a fire label drives the selection, Kwikset publishes UL 3 hour latches: the 83521 RCAL plain latch for BBL, KNL, CNL and PLL trims, the 83518 RCAL adjustable square drive UL 3 hour latch, and the 84290 square corner plainlatch with a 2-3/8 inch backset. Those are Kwikset components and will not be an MK Series lockset part, so confirm the host lock before substituting.
11) Will an Emtek deadbolt latch work as a replacement for the Arrow 115?
No. The Arrow 115 is a drive-in deadlatch for Arrow MK Series locksets, a mechanical latch driven into an existing bore. The Emtek LC9-DBLTCH is a motorized deadbolt latch in the EMPowered series, a powered deadbolt component rather than a lockset deadlatch, so it is not a swap for the 115.
12) What finish does the Arrow 115 deadlatch come in?
Satin chrome, 626, in both backsets. On a latch that matters less for looks than for matching the strike and lever trim already on the opening; 626 is the standard commercial finish and will read as a match against most satin chrome and brushed nickel MK Series trim.
13) Is the Emtek 83228 an alternative to the Arrow 115 for a pocket door?
They are different kinds of part. The Emtek 83228 is a faceplate and screws with square corners for a tubular pocket door privacy latch, so it is trim hardware, not the latch mechanism. The Arrow 115 is the deadlatch itself, supplied in 626 satin chrome for Arrow MK Series commercial locksets.
