Arrow 221 26D – Frequently Asked Questions

1) Will the Arrow 221 springlatch fit my existing door prep?
The Arrow 221 springlatch is built to a 2-3/8 inch backset with a 2-1/4 x 1 inch square corner face plate, so it drops into a standard MK Series door edge mortise without rework. If your door is bored on a 2-3/4 inch backset, the 221 is the wrong latch, and if the existing face plate is radius corner rather than square, the mortise in the door edge will not match.
2) Which Arrow locksets does the 221 latch work with?
It is a replacement latch for the Arrow MK Series lockset family, matched to MK Series door preparations. It is a parts-level component, not a complete lock, so you reuse the existing knob or lever trim and chassis.
3) Is the Kwikset 84290 plainlatch an equivalent to the Arrow 221 springlatch?
They share the same basic geometry but serve different lock platforms. The Arrow 221 springlatch is a commercial replacement latch built for the Arrow MK Series lockset family with a 2-3/8 inch backset and a 2-1/4 inch by 1 inch square corner face. The Kwikset 84290 is a square corner plainlatch with a 2-3/8 inch backset and is UL rated. If you are repairing an Arrow MK Series lock, use the 221; the Kwikset part is intended for Kwikset locksets.
4) What finishes does the Arrow 221 latch 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, match it to the existing lock trim on the opening so the edge does not read as a mismatched repair.
5) Is this a springlatch or a deadlatch?
The 221 is a springlatch, meaning the bolt is spring returned with no auxiliary deadlocking plunger. For an exterior or otherwise securable opening where the latch must resist being shimmed, specify a deadlatch instead. A springlatch is right for passage, classroom corridor and similar interior MK Series doors.
6) Is the Arrow 221 latch rated for commercial use and is it UL Listed?
Yes on both counts. The 221 is classified as commercial door hardware and is UL Listed, which is why it turns up in office buildings, schools, healthcare, retail and government facilities where the lock hardware on an opening has to stay within a listed assembly.
7) I manage a building with dozens of Arrow MK Series locks. Can I stock one latch for all of them?
If the doors are bored on a 2-3/8 inch backset and prepped for a 2-1/4 x 1 inch square corner face, one part covers them. Keep the finish you stock consistent with the trim on those openings, and check a few doors for 2-3/4 inch backset prep before you commit the order, since that prep needs a different latch.
8) I need a latch for a keyed entry lock, not a spring latch for an MK lockset. What are my options?
The Arrow 221 is a springlatch component for the Arrow MK Series lockset family and is not sold as a complete entry latch assembly for other locks. The Deltana DLE23875 drive-in latch is specified as an entry function and fits doors 1-3/8 inch to 2 inch thick, which is the closer fit if you need an entry-function latch rather than an MK Series service part.
9) Does the Emtek 83228 square corner faceplate work as a replacement for the Arrow 221 face?
No. The Emtek 83228 is a faceplate and screw set for a tubular pocket door privacy latch with square corners, so it is a faceplate kit only and is tied to the pocket door privacy latch. The Arrow 221 is a complete springlatch with a 2-1/4 inch by 1 inch square corner face for Arrow MK Series locksets. The square corner shape is shared; the parts are not interchangeable.
10) Which latch do I use for a deadbolt rather than a knob or lever lock?
The Arrow 221 is a springlatch, which retracts with knob or lever operation and is not a deadbolt part. For deadbolt work, the Kwikset 83521 is an RCAL plain latch rated UL 3 hour for BBL, KNL, CNL and PLL, and the Kwikset 83518 is an RCAL adjustable square drive UL 3 hour latch. The Emtek LC9-DBLTCH is a motorized deadbolt latch in the EMPowered series for electrified deadbolt applications.
11) Do I need a new strike plate when I replace an MK Series latch with the 221?
Not usually. The square corner face matches standard commercial door prep and standard strike plates, so an existing MK Series strike in the frame stays. Replace the strike only if it is worn or the finish no longer matches the new latch face.
