Arrow 101 5A – Frequently Asked Questions

1) Will the Arrow 101 5A springlatch fit my existing Arrow MK Series lockset?
Yes, the 101 5A is built as a replacement springlatch for Arrow MK Series locksets, with a 2-3/8 inch backset and a 2-1/4 x 1 inch square corner face. If your door is bored at 2-3/8 inches and the existing latch face is square cornered at that size, it drops into the same edge mortise. Doors prepped at a 2-3/4 inch backset need the longer-backset latch instead.
2) How do I know if I need a square corner or radius corner latch face?
Look at the latch face already in the door edge. The Arrow 101 5A has a square corner face measuring 2-1/4 by 1 inch, which matches doors mortised with a square cut. If your door edge shows rounded corners on the existing faceplate pocket, a square face will sit in a mortise that does not match and you want a radius corner latch instead. On a metal frame job the prep is usually square.
3) Can I replace just the latch instead of the whole lockset?
That is exactly what the 101 5A is for. It is a genuine Arrow replacement part for MK Series hardware, so when the latch stops retracting or springing back but the lever, cylinder and rose are still good, you swap the latch and keep the rest of the lock in the door. For a property manager or in-house maintenance crew that keeps the keying intact and avoids re-prepping the door.
4) Is there a square corner 2-3/8 inch latch that is UL listed for a fire door?
The Arrow 101 5A is the MK Series repair latch and no fire rating is carried with it, so do not put it in a rated opening on that basis. If the door is fire rated, look at the Kwikset 84290 square corner plainlatch, a 2-3/8 inch backset UL latch, or the Kwikset 83521 RCAL plain latch rated UL 3 hour for BBL, KNL, CNL and PLL lock lines. Those are Kwikset prep, not Arrow MK, so they do not interchange with an MK lockset.
5) Is the Kwikset 84290 plainlatch a substitute for the Arrow 101 5A springlatch?
They are both square corner latches with a 2-3/8 in. backset, so the door edge prep is the same shape, but they are not the same component. The Arrow 101 5A is a springlatch replacement part built for Arrow MK Series locksets and is offered in a 609 Antique Brass finish 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, UL rated, and is intended for Kwikset cylindrical locks. If the lockset in the door is an Arrow MK, order the Arrow 101 5A so the latch tailpiece and retractor engage correctly.
6) Is this a spring latch or a deadlatch, and does it suit an exterior door?
The 101 5A is a springlatch, so the bolt retracts under pressure and springs back when the door closes. There is no auxiliary deadlatch plunger described for it. That makes it right for MK Series passage and interior commercial openings; on a keyed exterior door where you are worried about the latch being shimmed, use a deadlatching latch instead.
7) I only need to replace the square corner face plate, not the whole latch. Is the Arrow 101 5A the right part?
The Arrow 101 5A is a complete springlatch assembly with a 2-1/4 in. x 1 in. square corner face, so it replaces the latch and face together for an Arrow MK Series lockset. If the latch body is sound and only the plate is damaged, a face plate only part such as the Emtek 83228 faceplate and screws with square corners for a tubular pocket door privacy latch covers that case on Emtek pocket door hardware. These are not interchangeable across brands, so identify the lockset first.
8) I have a mix of 2-3/8 in. and 2-3/4 in. backsets across my doors. What latch covers both?
The Arrow 101 5A is a fixed 2-3/8 in. backset springlatch for Arrow MK Series locksets, so it only suits the 2-3/8 in. openings. For an adjustable option, the Deltana DLP23875 drive-in latch adjusts to either 2-3/8 in. or 2-3/4 in. backset and is rated for doors 1-3/8 in. to 2 in. thick in passage or privacy function, and the Kwikset 83518 is an adjustable square drive latch with a UL 3 hour rating. Adjustable latches let you stock one part for both preps; the Arrow part keeps the MK Series lockset matched.
9) Does a fire rated opening change which latch I should order instead of the Arrow 101 5A?
The Arrow 101 5A is a commercial springlatch replacement part for Arrow MK Series locksets with a 2-3/8 in. backset. Where the opening requires a UL rated latch, the Kwikset 83521 RCAL plain latch is UL 3 hour rated and is specified for Kwikset BBL, KNL, CNL and PLL locks, and the Kwikset 83518 RCAL adjustable square drive latch is also UL 3 hour rated. Match the latch to the lockset brand and series already in the door, then confirm the rating against the door label.
10) Will the Arrow 101 5A work in a deadbolt?
No. The Arrow 101 5A is a springlatch for Arrow MK Series locksets, meaning it latches on closing and retracts with the knob or lever. A deadbolt takes a deadlatch or bolt assembly instead, such as the Emtek LC9-DBLTCH EMPowered motorized deadbolt latch in the EMPowered series. Do not order the 101 5A expecting it to fit a deadbolt bore.
11) What finish does the Arrow 101 5A latch come in?
One finish only: 609 Antique Brass. On a latch, the finish you see once the door is closed is just the faceplate in the door edge, so 609 matters most when you are matching other MK Series openings down the same corridor where the edges are visible on a held-open door.
