Arlington Industries 844 – Frequently Asked Questions

1) Will an Arlington 841 NM cable connector fit 12/2 and 14/2 Romex?
The 84X series clamps cable with an outer diameter from 0.225 to 0.612 inches, which covers the common NM sizes used in residential and light commercial branch circuits. Measure the flat cable across its wide dimension and check it falls in that window before ordering. The 841 is the 1/2 inch knockout version of that same clamp.
2) Can I run more than one NM cable through a single Arlington 84X connector?
That is the point of the 2-screw clamp design. The saddle pulls down over multiple NM cables in one knockout instead of forcing a separate connector and knockout per cable, which cuts the number of penetrations in a panel or junction box during rough-in. Each cable still has to sit inside the 0.225 to 0.612 inch OD range the clamp is built for, and total fill has to work for the box.
3) Is the Arlington 84X NM connector UL listed for use in a panel?
The 84X connector is both UL and CSA listed, which is what an inspector wants to see on an NM termination at a panel, junction box, or enclosure. It is made in the United States.
4) What size knockout do I need for a 2 inch Arlington NM connector, model 849?
Model 849 is the 2 inch knockout version, so it lands in a 2 inch trade-size knockout, typically a concentric or eccentric KO on a larger panel or gutter. The 84X range covers 1/2, 3/4, 1-1/4, and 2 inch knockouts, so match the model to the opening you actually have rather than reaming a box.
5) Is a 2-screw clamp NM connector better than a snap-in or push-in connector for panel work?
Different jobs. A 2-screw clamp like the Arlington 84X grips the cable jacket mechanically with a saddle and two binding screws, so it holds several cables at once and can be loosened and re-set if you have to pull a home run back out. Push-in connectors are faster on a single cable but are one-way. If you are bundling multiple NM runs into one knockout on a panel or subpanel, the 2-screw clamp is the one that does it.
6) Does the Arlington NM cable connector come with a locknut?
A locknut is part of the assembly on the 84X connector, along with the threaded body, clamp saddle, and two binding screws. You thread the body through the knockout from outside and tighten the locknut inside the box, then set the cable in the saddle and snug both screws.
7) Will a zinc die-cast NM connector hold up in a damp basement or an unheated utility room?
Zinc die-cast is what the 84X body is made from, a corrosion-resistant construction meant for long-term service in panels, junction boxes, and enclosures. The finish is silver. That said, it is an NM cable connector, and NM cable itself is a dry-location wiring method, so the connector should not be the reason you put Romex somewhere it does not belong.
8) Are these Arlington connectors made in the USA?
Yes, the 84X series NM cable connectors are manufactured in the United States. That matters on public and institutional work where domestic sourcing is written into the spec.
