That the typical Guy Ring is 1 & 1/4" and is larger than your mast pipe, doesn't matter. You still are going to have to drill a hole through the pipe and insert a long bolt through to hold the ring in place to prevent it from sliding down. So that will be the same. That there will be a slight little play between the ring and the mast will be negated by the tension applied from the guy ropes or wires. It will all do the job and stay in place once installed and finished.
Found an electric supply store local and I'll be on the air soon!!! Thanks to all for the "help"!!!
Wire Weasel, diameter of mast is 1/8" larger than guy ring...
