I guess i've never seen a bolt from the "dark ages" yet. But putting the arm on is a matter of prefernce, obviously. i've put them on both ways ( i get to a new local and see how they want it, and i deliver). and ive also had no problem installing or wrecking out a crossarm both ways metioned. gotta be versatile as a good lineman should be. and for the bolt it hold a cross arm that would be pretty heavy wire to snap it off.
highplanes i thought this was the dark ages, bucksqueeze, truck grounds, ncco cards ect...
everyone have a good one and work safe. and buy UNION!!!!!!!
Buy american made & when possible buy union made
