Arrow 104 26D – Frequently Asked Questions

1) Is this latch square corner or drive-in? I need to know before I pull the old one out.
Square corner faceplate, 2-1/4 x 1-1/8 inches, which is the standard commercial mortise-in-the-edge prep. It is not a drive-in latch. If your door edge has a round hole with no faceplate mortise, you want a drive-in style instead, like the Deltana DLE23875 entry latch or the DLP23875 passage/privacy latch, both of which carry an adjustable backset.
2) Is the Kwikset 84290 square corner plainlatch a substitute for the Arrow 104 springlatch?
Not for a 2-3/4 inch door prep. The Arrow 104 springlatch is built to a 2-3/4 inch backset with a 2-1/4 inch by 1-1/8 inch square corner face, while the Kwikset 84290 is a square corner plainlatch set up for a 2-3/8 inch backset. The square corner face geometry matches on both, but the crossbore-to-door-edge dimension does not, and the Arrow 104 is the part engineered as a drop-in for Arrow MK Series locksets. A plainlatch also has no spring return action, so it serves a different latching function than a springlatch.
3) What should I use if the door has no mortised faceplate pocket in the edge?
A drive-in latch suits that condition. 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 drive-in entry-function equivalent with an adjustable backset; both list a door thickness range of 1-3/8 inch to 2 inch. The Arrow 104 springlatch instead uses a 2-1/4 inch by 1-1/8 inch square corner face plate that sits flush in a prepared door edge, so it assumes a mortised faceplate pocket is already cut.
4) What finishes does the Arrow 104 latch come in so it matches my other MK Series hardware?
Six finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 625 bright chrome and 626 satin chrome. Match the latch face to the lever or knob already on the door, since the faceplate is the only visible part once the latch is installed.
5) Is the Arrow 104 a springlatch or a deadlatch?
It is a springlatch, meaning the bolt is spring-loaded and retracts on contact with the strike but has no deadlocking plunger. For an exterior or secured opening where you need the latch held against being carded, a deadlatch is the correct part, not this one.
6) I'm restocking latches for a building full of Arrow MK locksets. Do I need to specify handing?
No handing to call out on the 104. What you do need to specify is the finish, since it ships in six of them, and confirm every door is bored on the 2-3/4 inch backset. Springlatches are non-handed, so one part number covers left and right hand doors across the building.
7) Can I order the Emtek 83228 square corner faceplate instead of the Arrow 104?
No. The Emtek 83228 is a faceplate and screws for a tubular pocket door privacy latch, so it supplies the trim plate only and no latch mechanism. The Arrow 104 is a complete springlatch with a 2-1/4 inch by 1-1/8 inch square corner face and 2-3/4 inch backset. Both use square corner geometry, which is why they look interchangeable in a search, but only the Arrow 104 replaces the latching unit inside an MK Series lockset.
8) I need a fire-rated latch for a labeled opening - is the Arrow 104 the right part?
For a UL-rated latch component, the Kwikset RCAL line is the set that carries that call-out: the 83521 is a plain latch listed UL 3 hour for BBL, KNL, CNL and PLL locks, and the 83518 is an adjustable square drive latch listed UL 3 hour. The Arrow 104 is a commercial-grade springlatch built as a genuine Arrow replacement for MK Series locksets at a 2-3/4 inch backset, and it is the part to use when you are keeping that MK Series assembly and finish intact.
9) Does the Arrow 104 come with a strike plate and screws?
The 104 is sold as the latch unit itself, an Arrow genuine replacement component for MK Series locksets. If you also need a strike or a separate faceplate, order those as their own line items. For comparison, the Emtek 83228 is an example of a faceplate-and-screws-only part, sold without a latch body.
10) Will the Emtek LC9-DBLTCH work in place of an Arrow 104 springlatch?
No, they are different devices. The Emtek LC9-DBLTCH is an EMPowered series motorized deadbolt latch, meaning it is a powered deadbolt component. The Arrow 104 is a mechanical springlatch replacement part for Arrow MK Series locksets, built to a 2-3/4 inch backset with a 2-1/4 inch by 1-1/8 inch square corner face and offered in finishes including 626 satin chrome and 605 bright brass to coordinate with existing MK Series trim.
