HEYCO #2126 SB 875-11 BLACK SNAP BUSHING, for 7/8" Hole, Cable Mounting & Accessories, UL Recognized Component (Bag of 100)

I use these for running wires through drilled holes in metal. I like them because the snap in, and can be removed later. They don’t seal water tight, but I’ve put a bead of silicone in some to seal and they work just fine.

Installed metal stud framing and used a 7/8" carbide hole saw to cut hundreds of holes prior to assembly to run NM electrical cable, CAT, and COAX after the framing was up. Used the snap bushing wherever they were needed. They installed very easily into the 20ga and 25ga sheetmetal and none of them came out during the wire pulling stages. I would recommend.

Excellent product that I use on Marine generators

This fits the normal "1/2" hole in a metal electrical box (for 1/2" conduit fittings). I needed an insulator for the wires without needing a cable clamp. This works great and is easy to insert and remove.

For 1/2 knock out I use at work for bushing to prevent rubbing works great and way cheaper than home depot 5star

Theres a variety of electrical bushings you can get. These, I have used for years, whether its this size or the 7/8 inches. This particular one, you just need a half in drill bit and they snap right in place, and you can fit a few wire's in into it

1st order was for 100 pcs to test out the products. We liked it so much the 2nd order was for 3500 pcs. We will be ordering more soon.
