Arrow 101 26D – Frequently Asked Questions

1) Will the Arrow 101 springlatch fit a door bored for a 2-3/4 inch backset?
No. The Arrow 101 springlatch is built for a 2-3/8 inch backset only, so on a door prepped at 2-3/4 inches the latch face will not reach the door edge correctly. If your prep is 2-3/4, you need the matching 2-3/4 backset latch instead. For a job where the backset is uncertain, an adjustable drive-in latch like the Deltana DLP23875, which covers 2-3/8 or 2-3/4 inches, is the safer order, though it is a drive-in latch rather than an Arrow MK Series replacement.
2) Which Arrow locks does the 101 springlatch replace?
The 101 is a genuine Arrow replacement latch for the MK Series lock lineup. It is specified as an OEM component for those assemblies, so it drops into an existing MK Series lock without modification. It is not sold as a universal latch for other Arrow series or other brands.
3) Is my door edge cutout the right size for this latch face?
The face plate measures 2-1/4 by 1 inch with a square corner profile, which is the standard commercial door edge mortise cut. If your existing latch face is 2-1/4 x 1 inch and square cornered, the 101 seats flush with no filing or re-routing. If the old face has radius (round) corners, the square face will leave gaps at the corners of the mortise.
4) Is the Kwikset 84290 square corner plainlatch a substitute for the Arrow 101 springlatch?
Both are 2-3/8 in. backset square corner latches, so the door edge prep is comparable, but they are not the same part. The Arrow 101 is a springlatch built as a genuine Arrow replacement component for the MK Series lock lineup, with a 2-1/4 in. x 1 in. face. The Kwikset 84290 is a square corner plainlatch with a 2-3/8 in. backset sold for Kwikset cylindrical locks. If you are rebuilding an Arrow MK Series lockset, the 101 is the part engineered to that chassis; the Kwikset latch is intended for Kwikset locks.
5) I need a latch with an adjustable backset instead of a fixed 2-3/8 in. What are my options?
The Arrow 101 is a fixed 2-3/8 in. backset springlatch for the MK Series. When the door prep may be either 2-3/8 in. or 2-3/4 in., the Deltana DLP23875 drive-in latch has an adjustable backset of 2-3/8 in. or 2-3/4 in. in a passage/privacy function, and the Kwikset 83518 RCAL adjustable square drive latch is also an adjustable unit. Note the Deltana is a drive-in style latch for doors 1-3/8 in. to 2 in. thick rather than an Arrow MK Series replacement.
6) What looks like a replacement for the Arrow 101 but will not work?
A few parts sit nearby and are not interchangeable. The Emtek 83228 is a faceplate and screws only, for a tubular pocket door privacy latch with square corners, so it is trim rather than a working springlatch. The Emtek LC9-DBLTCH is a motorized deadbolt latch in the EMPowered series, a powered deadbolt component rather than a spring-loaded latchbolt. The Deltana DLE23875 is a drive-in entry latch for doors 1-3/8 in. to 2 in. thick, which installs without a mortised face plate. The Arrow 101 is the spring latch unit with a 2-1/4 in. x 1 in. square corner face made for the Arrow MK Series.
7) What finishes does the Arrow 101 springlatch come in?
Six finishes: 605 Bright Brass, 606 Satin Brass, 612 Satin Bronze, 613 Satin Bronze Oil-Rubbed, 625 Bright Chrome and 626 Satin Chrome. Since only the latch face shows on the door edge, pick the code that matches the MK Series lockset trim already on the opening so the edge does not read as a mismatch.
8) Is a springlatch the right choice, or do I need a deadlatch?
A springlatch retracts and springs back under the strike with no auxiliary deadlocking plunger, so it suits passage and interior openings in a commercial building. On an exterior or security opening, a plain springlatch can be shimmed or carded, and a deadlatching latch is the correct specification. The Arrow 101 is the springlatch for MK Series locks.
9) I need a square corner 2-3/8 inch latch but not for an Arrow lock. What else is there?
For non-Arrow work, the Kwikset 84290 is a square corner plainlatch at a 2-3/8 inch backset. A plainlatch is not a springlatch replacement for an Arrow MK Series lock, so use it only on the Kwikset locks it was built for. Stay with the Arrow 101 when you are restoring MK Series hardware.
10) Can I standardize one latch part number across a building full of Arrow MK locks?
Yes, if every opening is prepped at 2-3/8 inch backset with a 2-1/4 x 1 inch square corner face. In that case the 101 is the single latch to stock, ordered in the finish that matches each floor's trim. Openings prepped at another backset or with radius corner faces need a different latch and should be logged separately.
11) Does the Arrow 101 springlatch carry a fire rating, or do I need a different latch for a fire door?
The Arrow 101 is described as a commercial-grade genuine Arrow replacement springlatch for the MK Series with a 2-3/8 in. backset and square corner face. Where the opening requires a labeled latch, the Kwikset 83521 RCAL plain latch and the Kwikset 84290 square corner plainlatch are both UL latches, and the Kwikset 83518 RCAL adjustable square drive latch is a UL 3 hour latch. Those Kwikset latches are for Kwikset lock chassis, so confirm the lock they are going into.
12) I need a privacy or passage latch, not a keyed-entry springlatch. What should I look at?
The Arrow 101 is the springlatch used to restore Arrow MK Series lock assemblies. If the function you need is privacy or passage, the Deltana DLP23875 drive-in latch is a passage/privacy function with an adjustable 2-3/8 in. or 2-3/4 in. backset; the Deltana DLE23875 is the entry function version of that drive-in latch. The Emtek 83228 covers privacy/bed/bath as a square corner faceplate and screws for a tubular pocket door privacy latch.
13) I only need to replace a damaged latch faceplate, not the whole latch. Is the Arrow 101 the right part?
The Arrow 101 is the complete springlatch unit, including its 2-1/4 in. x 1 in. square corner face, supplied as a genuine Arrow replacement part for MK Series locks. If the latch itself works and only the trim is damaged, a face-only part such as the Emtek 83228 faceplate and screws for a tubular pocket door privacy latch is the kind of component to look for, though that one is an Emtek pocket door part and not an Arrow MK Series piece.
