robust service drop at shallow angle

I am moving my service drop from a very bad place to the end of my garage. It will attach to the side of the building near the peak. The service drop going back to the pole will be only 17 degrees from the house - pulling sideways.

The only anchor I can find (and what is specified by the power company) is a porcelain insulator with a four inch long, 3/8" (or so) lag screw. A similar insulator on the present location, is much less sideways, perhaps 40 degrees, and it has been pulled and bent sideways. to point at the pole.

Is there an anchor designed for such a location, or can someone point me to a similar insulator that has a fat, long bolt? I am thinking that I can bridge several studs with plywood inside to spread the load and put this through the entire wall.

Any suggestions on how to handle this better would be greatly appreciated.

Thanks.

You need something similar to this but with an insulator attached.

Yep. Two questions:

[1] Two questions: Where would I find one? Often the key to finding something is knowing the right words ... "Thingy" doesn't usually search well!

[2] It seems to me that I should put it diagonal through a board backing up the sheathing so as to point toward the pole (somewhat), so that it is not being pulled at an angle. Yet I don't imagine pros do this... what would a pro do who wanted to "do it right"?

Thanks.

Not very many big box store will have this item in stock but electrique supply centre will have it with serveral rod lengths which it can poke thru the stucture member { make sure you have good stucture member there otherwise you may need a 4X4X 1/8 or 1/4 inch steel plate with centre hole bored out}

If you have 2X4 good structure then I will suggest to " sister " up aka double up to make it stronger. otherwise the other option is use the angle iron and it will cover few 2X4 to spread out the tenstion. { this is my refered choice when you have pretty long drop or awkard angle }

Naw most case I use the correct holder and properly attached as I explain above and how far is the pole to the house some case the length may change the way it will attached.

Oh yeah ., Just don't attached on the sheet of plywood or plankboard they will come off pretty fast once the strong wind storm or ice coated the service drop.

Thanks.

Merci,

How about a 19" piece of 2x4 fastened with screws horizontally on the outside spanning two studs, and the lag bolt insulator unit goes through the 2x4 at a 30 to 35 degree angle more or less pointing at the utility pole.
