Arlington Industries 841ST – Frequently Asked Questions

1) Will the Arlington 841ST NM cable connector fit a standard 1/2 inch knockout on a metal box?
Yes. The 841ST is a 3/8 inch trade size connector, and the threaded hub goes into a 1/2 inch knockout, which is the standard small knockout on metal device boxes, panels, and enclosures. Secure it with the locknut on the inside of the box.
2) What size NM cable will the Arlington 841ST clamp hold?
The clamp accepts cable with an outside dimension from 0.225 to 0.612 inches. Measure the flat (minor) dimension of your NM-B cable against that window before you order. Cable outside the 0.225 to 0.612 range will not clamp correctly, and the two-screw clamp is what lets you bring more than one cable through the same fitting when the combined profile still falls in range.
3) Can I run two NM cables through one Arlington 841ST connector?
That is what the two-screw clamp is built for - it is a multi-cable support fitting. The limit is the clamp opening: the cables together have to sit inside the 0.225 to 0.612 inch range. Two flat runs of small-gauge NM will typically stack inside that window; larger cable will not, and gets its own fitting.
4) Is this Arlington zinc NM connector UL and CSA listed for code work?
It carries both UL and CSA listings, so it can be used on inspected residential and commercial work on either side of the border. It is made in the United States.
5) Why choose a zinc die-cast two-screw NM connector over a plastic snap-in fitting?
Two different tools. A snap-in plastic connector is a one-cable, push-and-go fitting for speed. The 841ST is zinc die-cast with a two-screw clamp, so it grips the cable jacket mechanically and holds more than one run in a single 1/2 inch knockout. Go zinc with a clamp where you want a mechanically held connection, a metal body in the box, or where the cable may get pulled on after it is terminated.
6) Is the Arlington 841ST suitable for a wet or corrosive location?
No. It is a zinc die-cast clamp connector for NM cable, and NM-B itself is a dry-location-only wiring method, so the fitting belongs in dry interior work: residential rough-in, commercial tenant space, office and retail boxes, light industrial cable securing. For damp or wet locations you need a listed watertight fitting and a different cable type.
7) How much room does the Arlington 841ST connector take up inside the box?
The fitting body measures 0.880 by 0.920 inches and each piece weighs 0.044 lbs. That footprint matters when you are ganging several connectors along the side of a 4-square or a shallow device box - lay out your knockout spacing so the clamp bodies and locknuts do not collide.
8) How do Arlington 841ST connectors come packaged for a bulk job?
They ship 100 pieces to a unit carton, with 1000 pieces to the standard case. For a multi-family or tenant build-out where you are feeding dozens of panels and boxes, the 1000-piece case is the usual buy.
