huh... never seen it, didn't know it existed.

truth be told, i see it as a solution for a problem that doesn't exist,
plus creating two brand new problems all its own:

1. the screws disappearing in transit. now, you can stop and look
for screws that fit, or carry THOSE with you.....

2. a bundle of this is gonna be bulgy and awkward, and i'll bet a
cheeseburger that handling bumps and stuff hitting those screws,
and tweaking them enough to deform the "coupling" enough that
the pipe won't slide into it.

as far as being "faster", i doubt it. i can put couplings on and tighten
them down pretty quickly with a screw gun, or small impact driver.
and this removes one of the install advantages of emt.... bend and
cut to fit... doing racks of emt, and wanting to have the couplings
line up, in exposed work, is pretty effortless. bend your 90's to fit,
get them all around the corner, and then cut all the ends even with
the shortest one. continue running emt.....

with this, you get to do developed length and bend, which isn't as
fast as plan A, to save a largely worthless coupling.

this seems to be an idea developed in marketing by folks who've
never actually done this for a living.

interesting, but a solid -1 for me.

Well,I will tell them to close the factory, me and the guys that have never used it decided it is no good. :p

I have never used those but have seen them in place in existing buildings. I have used a few couplings and connectors with the screws lined up that way and don't like them. Dual screws should be side by side, around the curve. Lined up like that, 1 often loosens the other. Tighten 1st one snug, go to 2nd and snug it down. Then the 1st is loose again. On it goes. Sometimes can bend the lip down and make a rough edge inside. That would probably not be an issue on rigid but can be on EMT.

You still have to have some couplings too, for cut pieces.

We buy high volumes of pvc sweeps and the price difference on a bell vs. straight is shocking.

Check it out with your supplier and see how much they're charging you each way and make an informed decision.

When installing Schedule 40 or 80 what determines whether the electrician will get pipe with belled ends or use couplings? Thanks.

Around here, the decade it was manufactured. :lol: I haven't seen non belled ends since 1974



Crap....old post but, same answer

Plumbing PVC can have bell ends too.

Did you ever notice that a stick of PVC measures ten feet including the bell. That means if you glue up a bunch of PVC and then go back and count the sticks to get a length for you wire you end up with a lot of extra wire on one end of your run?

I don't think plumbers ever run into such a problem.
Sure they do. They just end up with a lot of extra water.
