Arrow 114 26D – Frequently Asked Questions

1) Will the Arrow 114 deadlatch fit a door prepped for a 2-3/4 inch backset?
That is exactly what the Arrow 114 is built for. It is a 2-3/4 inch backset deadlatch, so the cross-bore centerline sits 2-3/4 inches from the door edge. If your existing prep is the other common commercial backset, 2-3/8 inches, the 114 will not line up and you need a 2-3/8 inch latch instead.
2) What size faceplate does the Arrow 114 latch have, and will it drop into my existing mortise cutout?
The face measures 2-1/4 x 1-1/8 inches with a square corner profile, which matches a standard square-corner edge prep. If the door edge was routed for a radius (round) corner faceplate, the square corner will leave gaps at the corners unless the mortise is squared up.
3) Is the Arrow 114 deadlatch a direct replacement for an Arrow MK Series lockset?
Yes. The 114 is the genuine Arrow replacement latch for the MK Series lockset family, dimensioned to match the original so the existing door prep and lockset body are reused as-is.
4) What is the difference between the Arrow 114 deadlatch and the Kwikset 84290 square corner plainlatch?
Both use a square corner face, but they are different latch types on different door preps. The Arrow 114 is a deadlatch built for the Arrow MK Series lockset family, with a 2-3/4 inch backset and a 2-1/4 inch by 1-1/8 inch face. The Kwikset 84290 is a plain latch with a 2-3/8 inch backset. A deadlatch carries a deadlocking plunger alongside the latchbolt for use with a strike that holds it depressed; a plain latch does not. If the door is bored 2-3/8 inch, the Arrow 114 will not reach the strike.
5) My opening needs a UL fire rated latch. Is there an alternative to the Arrow 114?
For a fire rated opening, the Kwikset 83521 RCAL plain latch is UL 3 hour rated and fits Kwikset BBL, KNL, CNL and PLL locksets, and the Kwikset 83518 RCAL adjustable square drive latch is also UL 3 hour rated. Both are Kwikset lockset parts rather than Arrow MK Series components, so they will not mate with an MK Series lock body - the substitution is at the whole lockset level, not the latch alone.
6) What finishes can I get the Arrow 114 latch in to match the rest of my hardware?
Six finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 626 satin chrome, and 630 satin stainless steel. Match the faceplate finish to the lever or knob trim already on the opening, since the faceplate is the only visible part once the latch is installed.
7) What is the difference between a deadlatch and a plain latch, and which do I need?
A deadlatch carries a small auxiliary plunger alongside the latchbolt. When the door closes, the plunger hits the strike and locks the latchbolt against being shimmed or carded, which is why it is used on exterior and secured commercial openings. A plain latch has no deadlocking plunger and is for interior passage or privacy use only. The Arrow 114 is a deadlatch for commercial applications. If you only need a non-secured interior latch, something like the Kwikset 84290 square corner plainlatch covers that.
8) Can I standardize on the Arrow 114 latch across a building's commercial openings?
Yes, provided the openings run Arrow MK Series locksets on a 2-3/4 inch backset with square corner edge prep. Stocking one latch in one finish covers every door that meets those three conditions, which is what facility maintenance groups in offices, schools, healthcare, and multi-tenant residential typically do. Mixed backsets across the building will need a second part number.
9) The door is a passage or privacy opening, not a keyed one. Does the Arrow 114 work there?
The Arrow 114 is a deadlatch, which is intended for keyed locksets in the Arrow MK Series where the deadlocking plunger rides against the strike. For a non-keyed opening, the Deltana DLP23875 is a passage/privacy drive-in latch with an adjustable 2-3/8 inch or 2-3/4 inch backset for doors 1-3/8 inch to 2 inch thick. The Deltana is drive-in rather than face-plate mortised, so confirm the door edge prep before ordering.
10) I only need to replace a damaged face plate - do I have to buy the whole Arrow 114 deadlatch?
The Arrow 114 is supplied as a complete deadlatch with its 2-1/4 inch by 1-1/8 inch square corner face, so the face is not sold separately from the latch. Face plate only parts do exist in other lines - the Emtek 83228 is a square corner faceplate and screw set for a tubular pocket door privacy latch - but that is an Emtek pocket door privacy part and will not fit an Arrow MK Series deadlatch. For the MK Series, replace the 114 as an assembly.
11) Can the Arrow 114 be used with an electronic or motorized lock?
The Arrow 114 is a mechanical deadlatch made as a direct replacement for Arrow MK Series locksets, with no electrified function. Motorized latching is handled by purpose-built parts such as the Emtek LC9-DBLTCH EMPowered motorized deadbolt latch, which is a deadbolt latch in the Emtek EMPowered line rather than an MK Series latchbolt. The two are not interchangeable in the same door prep or lock body.
12) Do I need a new strike when I replace the latch with an Arrow 114?
Usually not. Because the 114 matches the MK Series original in backset and faceplate size, the latchbolt returns to the same position in the frame and the existing strike keeps working. Order a strike only if the old one is damaged or the frame prep was modified.
13) Is the Arrow 114 handed, or will one part work on left and right hand doors?
Cylindrical deadlatches of this type are non-handed; the latchbolt is reversible so one part serves either swing. What you do need to confirm is the backset, 2-3/4 inches here, and the square corner faceplate profile.
