Wondering how many of you out there have seen or needed to use a5" Chase nipple, locknut and bushing? And is there any sites to possibly get a used one, any knowledge of cost? Thank you.

I've never had a need for one, but I just went online with my main supply house and I could have one next day for almost 300 bucks. I think I'd find another way. For very large openings, instead of using a chase nipple, I use QuickEdge type molding. Panduit, T&B, and many of the majors make something similar.

Damn, you would be tightning that badboy with a hammer and a beater.

Thanks for the info! I also looked online and found one with 2 locknuts and plastic bushing for around $300. That's crazy that they make them available. I was curious all of sudden because I came across a full setup that I had demo'd out of an old CT cabinet years ago. It's in perfect condition.

Why not just use allthread? I got a hog. I'll only charge you $300...........

Running thread nipples aren't technically legal.

Running thread nipples aren't technically legal.

let me guess, UL white book? the same one that prevents us from using a threaded coupling, and EMT connector and LFMC connector to transition raceways, but we do it anyway.

Yeah, I know, but I won't tell on him if you don't.

Nope. The NEC. In several places.

Pipe taper. Running thread doesn't taper.

then why is allthread conduit used by electricians?

Pipe taper. Running thread doesn't taper.

So a close nipple would be compliant, because it has a taper? The locknuts dont care, actually, its more difficult to get the locknuts to set on a taper.

I didn't write the code. Nobody trusts me . Even Miller wouldn't make me a moderator.

Close nipples actually have taper toward the center.

There is UL listed running thread conduit that you can cut a hunk off of. Picoma (Beck) makes some. I'm just not sure how you compliantly use it.

I think the main objection to running threads came in the pre-EMT days, when installers would run a ton of thread on a pipe to spin a coupling on the whole way, and then center it up when the next piece was butted up to it, to avoid using an Erickson coupling.

That makes sense. Now I understand why I saw that very same thing on a rigid conduit run that was installed in a very old building. I seem to remember it was 3", so im sure that would have been a very expensive erickson.

I have listed PVC all thread.
