John: My calipers shows 0.55 inch diameter for the hole in the torque
bar, so it looks like the bigger shackle will fit. It sure doesn't
inspire me that Rohn can't provide an explanation for why they limit the
guy size to 3/16 in EHS.

This does not appear to be a big issue. There are 3/8 shackles (the size
recommended for your torque bar) that have a higher breaking strength than
your 1/4 EHS. Did you measure the hole size to see if a larger shackle will
fit? A 7/16 shackle has a Ø1/2 pin.

All Rohn 45G tower designs require 1/4 in EHS on at least one of the
guys. My 50 ft install uses a single 1/4 in EHS guy, presumably
precluding the use of torque bars. He was not certain, but suspected
the issue was simply that the shackle required for 1/4 in EHS would not
clear the hole in the bar. I also have this guy bracket:

except that mine has $1000+ worth (!) of torque bars in place of the
ringfills and eyelets. I asked about ordering those to replace the
torque bars and he said it would be cheaper to just buy the entire
bracket assembly. He also said to investigate getting substitute eyelet
hardware from another vendor.
I'm open to suggestions.
