Default panel mounting on a round light pole

I am installing lights for a football field. I am looking for ideas how to get a load center to mount to a round steel pole. Any ideas for a neat yet solid installation??

I concur ^ ...edit: (but I'd skip the strut)

I'd add a couple of self tappers thru the panel into the pole too.

Slip some tubing over the all thread?

It will mount to the pole with self tappers lined up vertically but someone could twist it off if they wanted to....unless it was a rather large pole.

How about heat shrink over the 3/8 all thread to protect the pole?

This is exactly how I would do it also.

Red Flag!!!!!

Does 'bronze' mean this is a manufactured steel light pole?

You'd better check with the manufacturer if so.

Spend a buck, homemade "U" bolts look bad, are weak and look unprofessional. You can get any size of stainless "U" bolts at a plumbing supply house.
Also pay heed to 480sparkys post.

They are manufactured steel light poles with a bronze finish. Do you think the manufacturer would have a suggestion?

bending all thread weakens it significantly (bad practice)

the manufactured u bolt idea is nice, or you could also have a local fabricator make you some thru bolted flange for mounting (sometimes done when new steel has to be added to existing round columns, although probably overkill for your application)

It's pretty clear; all thread is designed for tension loads. It is not rated to be formed into a U shape. If you need a U bolt buy a U bolt.

You got to be kidding, bending all tread bad practice? I have 30 yr installs done just the way I explained it. I'm sure if the OP wanted to go into structural engineering for this simple panel mount he could try e-mailing NASA. Most times simple is best. And if there is the right size and place to get the U bolt just as good.But I doubt easy to find.

The manufacturer's suggestion would be "Don't".

i have to disagree. the rating of the all thread may be compromised, but, more specifically on a wooden pole, the panel isn't budging without some extra assistance, i.e., sledgehammer, car, etc. at which point nothing is gonna help

Don't mount a panel on the pole?

Again, I concur^

Bending all thread will make NO difference in this application. The nuts would strip off before the rod broke.

ANY size? This pole could be 12" diameter. Stainless is a far superior product but it's not necessary. If it was readily available I'd use it but I wouldn't spend a lot of time looking for it.

Paint the all thread bronze and move on.
