A caution, though. I used these clamps for my tower leg ground wires.
After a year the small screws that pinch the copper wire have rusted, and
all the wires are loose! Not exactly a good lightning ground. If you wind
up with ones like I did, I suspect they could be a problem up on the tower
unless the offending area is potted with some sort of tar-based compound -
at which point the problem is how to inspect the joints... ah well.
