Arlington Industries NM904 – Frequently Asked Questions

1) What size knockout does an Arlington NM900 series snap-in bushing fit?
Arlington's non-metallic snap-in knockout bushings are ordered by trade size, one part per knockout: NM900 for 1/2 inch, NM901 for 3/4 inch, NM902 for 1 inch, NM903 for 1-1/4 inch, NM904 for 1-1/2 inch, and NM905 for 2 inch. Match the number to the knockout you punched, not to the cable or conduit running through it.
2) Are Arlington non-metallic snap-in knockout bushings UL listed for inspection?
They carry both UL and CSA listings, which is what an inspector looks for when you have used a bushing to protect conductors passing through a punched knockout. Useful on institutional and government jobs where every fitting in the panel has to be a listed component.
3) Do I need a locknut or any other hardware to install these knockout bushings?
No extra hardware. The bushing snaps into the knockout and holds itself, so there is no locknut, screw, or threaded body to chase on the back side of the box. That matters when the enclosure is already mounted and you cannot get a hand behind it.
4) Should I use a plastic snap-in bushing or a metal grounding bushing on a knockout?
These Arlington bushings are plastic and non-metallic, so they protect conductors from the raw edge of a knockout and nothing more. They do not carry a bonding path. Where the fitting itself has to be part of the equipment grounding path, or the raceway needs bonding to the enclosure, you want a metallic grounding bushing with a lug instead. For an open knockout that is simply passing cable, the non-metallic snap-in is the right part and it eliminates any galvanic pairing with the enclosure.
5) Will these bushings work in a panel or enclosure that already has cable run through it?
Yes, and that is the common retrofit use. Because the bushing snaps in from the front rather than threading on with a locknut, you can protect an open knockout on an enclosure that is already mounted and wired. Punch or find the knockout, push the matching size in, done.
6) Are Arlington NM900 knockout bushings made in the USA?
Made in the United States by Arlington Industries. That answers the domestic-content question on federal, municipal, and other publicly funded work where sourcing has to be documented.
7) Will a plastic knockout bushing hold up in a damp or corrosive electrical room?
The body is plastic, so it will not rust or corrode and it will not set up a galvanic reaction against a steel or aluminum enclosure. That is the usual reason to spec non-metallic over a metal bushing in mechanical rooms, parking structures, and coastal facilities. It is a knockout protector, though, not a sealing fitting, so it does not by itself make an enclosure watertight.
8) What color are these Arlington snap-in bushings, and is there another color option?
Black is the only color. The six part numbers differ by trade size alone, from 1/2 inch through 2 inch, so a property manager standardizing a stock room only has to decide sizes, not finishes.
