This is a very common problem in the commercial tower industry. One
common solution, which I initially (decades ago) rejected as being crude
but gradually came to accept as elegant, is to use bent (or curved)
saddles and all thread rods (or bolts). Or, if you want a close fit
because of worries about thin walled tubing deforming, use double
muffler style clamps and all thread bolts.

I have a similar problem - McMaster 3/8 and 1/2" hot dip galvanized
u-bolts regular length are too short and extended length are too long.
Also, 3" tubing sizes are not stocked, only IPS sizes. However, if one
goes with 1/2" rod, Portland Bolt will make whatever you want. Haven't
tried it, so I don't know pricing/lead times.
DX Engineering sells the Cycle 24 muffler style (they call them economy
saddle clamps), they are hot dip galvanized, and good lengths and
diameters for elements to booms or booms to masts plates.
The Fastenal & Grainger lines are weak, so it would be nice to find some
sources with more choice.

Hello-
I am having trouble finding some HDG 3/8" size long-shank U-Bolts.
I need ones with around 5" of straight 3/8" bolt, before the bend
starts. Does anyone know of a source?
Thanks, Byron WA5THJ
