Ron, you are caught up in the Shackle working load vs guy cable breaking
strength quandary. Typical breaking strength (actual number undocumented) is
four to five times the working rating.
If you accept this, then the 2000 lb rating of the shackle is sufficient.

I am using Rohn 45 Torque bars and having trouble attaching the guy wire to
the torque bar. I am using phillystran and using big grips. The big grips
just goes through the torque arm 1/2 inch hole and thire is no room for a
thimble.
If I use a 3/8" Shackle they are rated only at 2,000 lbs. That dont seem
enough. The Phillystran is rated at 6,700 lbs.
What are your suggestions ?
Ron
