POCO makes us back brace 2" IMC over 36". I hate doing it but sometimes we need some extra height to clear an obstacle.

Braces are 3/4" EMT hammered flat and drilled. Braces must be bolted through the rafters. If there is enough room in the attic space it's not too bad.

I generally I locate the rafters from above with long drywall screws then drill down.

This one had some room in the attic so I drilled up, tapped in a carriage bolt, bolted down a 4s blank as a washer and bolted the brace to the remaining stud.




The hole is drilled exactly the same size as the bolt for a tight fit and the blank is caulked and bolted down snugly to the shingle to (hopefully) prevent a leak.

The 4s cover does look a little hacky so I am looking for something as big to take it's place.....maybe something galvanized. I tried washers before but they sucked into the shingle too much and I ended up splooging caulk all over them to seal them up.

Use your tin snips to cut the corners off the blank, like an octagon. It would look spiffy then.

I say that's a decent job.
Why so overbuilt though? We just use wire rope straight back to an anchor. Are you required to triangulate that way?

You also forgot the rubber on the roof boot....not that it rains there.

Nice looking job and a great idea. I always just used steel cable but I like your way better.

You think tin snips will cut a blank cover???



We dont use rubber boots here. If it leaks it just runs down to the top of the exterior panel anyway. ...and it IS raining today

POCO specs. two 3/4 EMT braces, thru bolted, 45 degrees.

Is the riser EMT?

Do you paint it when you are done? A couple coats of Cold Galv would do the trick. I have seen my buddy use a bracket like that to support a Class A chimney. He was using a kit that he bought from his supplier and the kit used 3/4 EMT. He now makes his own and saves money.

IMC

Absolutely

There is no way you could cut the 4" blank with tin snips and make it look good IMO

Maybe a plumbing supply might have a round flange you could use

Nice looking job. Solid and secure. keep the POCO happy.

But IMC- I would think 'Rigid' nothing less.
We don't get a lot of those installations here, Usualy a good solid side of the house to secure to.

I have seen water cause a lot more damage than electrical in the past.

I would definitely have put a 'boot' on the riser.

After all that- what, maybe a 35% inrease on a service price?

After all... I aint a roofer, I sub that out.

We do the same thing here in California. However, instead of EMT we use 3/4" IMC for the braces and IMC for the riser too. You think his is overbuilt, you should see mine!

I haven't even seen a stick of rigid in twenty years.


I put a roof jack on it, just not a rubber one. There is like a 1/64" clearance which is caulked.

The panel is outside and the IMC runs into a factory hub.

The only place that stocks rigid is Lowe's . The supply house is all IMC. Quite a bit heavier.

Which of the 3 black wires is the noodle?

Simply untrue. A good pair of snips will cut easily and cleanly through a 1900 blank. Try it sometime. I made some large KO seals from blanks just the other day.

I've never tried to cut a blank cover, but mine will easily cut fender washers.
