Arrow 104 5A – Frequently Asked Questions

1) Will the Arrow 104 5A springlatch fit a door bored for a 2-3/8 inch backset?
No. The Arrow 104 5A is a fixed 2-3/4 inch backset springlatch, so it only drops into a door prepped at 2-3/4 inches from the door edge to the center of the bore. If your opening is prepped at 2-3/8 inches, you need a 2-3/8 inch latch instead. An adjustable drive-in latch such as the Deltana DLP23875, which covers both 2-3/8 and 2-3/4 inch backsets, is one way to cover an opening where you are not sure which prep you have.
2) What lock does the Arrow 104 5A springlatch replace?
It is a service part for Arrow MK Series locksets. Arrow built the 104 5A to match the MK Series prep exactly, so it goes back into an existing MK installation without reworking the door. If the lock on your door is a different Arrow series or another brand, this is not the latch for it.
3) Does the Arrow 104 5A latch have a square corner or radius faceplate?
Square corner. The face measures 2-1/4 x 1-1/8 inches with square corners, which is the standard commercial door edge prep. If your door edge is routed with a radius (round corner) mortise, a square face will not sit flush and you would need a radius corner latch or a separate faceplate.
4) If the door is prepped for a 2-3/8 inch backset instead of 2-3/4 inch, what square corner latch should I order?
The Arrow 104 5A is a 2-3/4 inch backset springlatch with a 2-1/4 inch by 1-1/8 inch square corner face, so it will not reach the strike on a bore drilled at 2-3/8 inches. For that prep, the Kwikset 84290 is a square corner plainlatch with a 2-3/8 inch backset and a UL listing. Note the difference in latch type as well: the Arrow 104 5A is a springlatch for Arrow MK Series locksets, while the Kwikset part is a plainlatch intended for Kwikset cylindrical locks, so it is a backset-correct alternative rather than an MK Series replacement.
5) Is there a latch that covers both 2-3/8 and 2-3/4 inch backsets so I can stock one part?
The Arrow 104 5A is a fixed 2-3/4 inch backset springlatch built specifically for Arrow MK Series locksets. If you want one part that covers both common bore dimensions, 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 the adjustable drive-in latch in an entry function. Both Deltana latches are drive-in style rather than face plate style, so they seat in the bored edge hole and do not use the 2-1/4 inch by 1-1/8 inch square corner mortise the Arrow part requires.
6) Is this a springlatch or a deadlatch?
The Arrow 104 5A is a springlatch, meaning a plain beveled latchbolt with no auxiliary deadlocking plunger. It retracts on the strike and springs back out, so it suits interior and passage style openings on MK Series locks rather than exterior doors where a deadlatching latch is normally specified.
7) Do I need to change the strike when I put a new Arrow 104 5A latch in?
Not if you are replacing like for like in an existing Arrow MK Series lock. The 104 5A carries the same 2-3/4 inch backset and 2-1/4 x 1-1/8 inch face as the original, so the latch lands in the same spot in the frame and the existing strike stays. You are only swapping the latch unit itself.
8) I am standardizing latches across a building. Is there an adjustable option instead of buying two backsets?
The Arrow 104 5A is fixed at 2-3/4 inches, so on Arrow MK Series openings you order to the prep you have. Where you are working on non-Arrow tubular openings and want one part to cover both preps, the Deltana DLP23875 drive-in latch is adjustable between 2-3/8 and 2-3/4 inches in a passage/privacy function, and the Deltana DLE23875 is the entry function version; both are listed for doors 1-3/8 to 2 inches thick.
9) I need a UL rated latch for a fire door. Is the Arrow 104 5A the right part?
The Arrow 104 5A is a commercial springlatch made as a direct replacement for Arrow MK Series locksets, and it should be specified against the MK Series lock it is servicing. Where the requirement on the drawing is an explicitly UL rated latch, the Kwikset 83521 is an RCAL plain latch rated UL 3 hour for Kwikset BBL, KNL, CNL and PLL locks, and the Kwikset 83518 is the RCAL adjustable square drive version with the same UL 3 hour rating. Those Kwikset latches fit Kwikset lock chassis, not Arrow MK Series, so confirm which lock is in the door before ordering.
10) What is the difference between the Arrow 104 5A and a deadbolt latch like the Emtek LC9-DBLTCH?
They do different jobs on the door. The Arrow 104 5A is a springlatch, meaning the bolt is beveled and retracts when the door closes against the strike, which is what a latching lockset needs to self-latch. The Emtek LC9-DBLTCH is a deadbolt latch in the EMPowered series and is motor driven, so the bolt is thrown and withdrawn by the lock rather than by contact with the strike. A deadbolt latch is not a substitute for the springlatch in an Arrow MK Series lockset.
11) My square corner face plate is damaged but the latch itself works. Do I need the whole 104 5A?
The Arrow 104 5A is supplied as a complete springlatch with its 2-1/4 inch by 1-1/8 inch square corner face, so ordering it replaces both the latch body and the face plate on an Arrow MK Series lockset. If the opening in question is a tubular pocket door privacy latch rather than an MK Series lockset, the Emtek 83228 is a face plate and screws kit with square corners sold on its own for that application. The Emtek kit is specific to Emtek tubular pocket door privacy latches and does not fit the Arrow part.
12) What finish does the Arrow 104 5A latch come in?
One finish only: 609 Antique Brass. On a latch the finish only shows on the faceplate at the door edge, so if the rest of the MK Series lock on that door is Antique Brass the edge will match. If your opening is in a different finish, the visible faceplate will not coordinate.
13) Is this Arrow latch rated for commercial traffic?
Yes, the 104 5A is a commercial grade part, built for the cycle counts you see in office buildings, schools, healthcare, retail, multi-tenant housing and government facilities. It is the same latch Arrow supplies in the MK Series lockset, not a light duty residential substitute.
