I need to layout a plan for rigid 4", can someone
measure the outside Dia. - cutting teeth to cutting teeth? It's a tight panel size dealing with
300.14 , &. 314.28.

Thanks for your help !

Don't forget to leave room for bushings.

Yes, thanks if I know worst size then wouldn't
the bonding bushing at least be 1 to 1 with
Lockable below?

Hard to say. Bonding bushings have a set screw and a ground lug that sometimes you can't really help where they land when you spin them on. I'd avoid the bonding bushings unless you needed them per code. If it's a feeder that could be a pretty large ground wire depending on the amount of runs and ocpd

There's no shame in grinding down the ridges of a lock ring. Okay maybe a little.

My old boss made me do it once, I spent 2 hours grinding and filing until it fit lol

5.32" although you're probably all set.

We've all done it at least once.

Wow, thanks 5.32" seems small I went and them only had up to 2.5" at
Box Store. That measurement was .3/8" of the side of a meaty looking lock
nut.

So I'll prepare a 3D sketch!

Thanks everyone!

There saying 5.9/32". This seems a lot more to real! I was going to give
.5/8" to .3/4" allowance with 4.5" D. pipe. so it's really +.9/16" per side!

Sorry to hang out the Trash.... Ah trying to make someone look smart and not shave any locknuts, LOL!
