Thanks for the info,.
I have not contacted the building code office as I assumed that in the County that there would not be Code requirements on a batting cage, I could be wrong.
Not being an engineer myself I did not know the best way to approach this issue.
I do have a person working on this for me, after I placed the initial post here.
Here is the site that shows the setup I am trying to emulate, save the piping. http://www.battingcagesinc.com/inde...attingCage
I do think that the long side, 72 ft vs the shorter 14 ft would require that I rotate the majority of the most rigid angle of the Ibeam toward the 72ft run to offset the uneven load being put on the cable for the longer run.
I may even just turn the ibeam direct toward the long side and place a pipe across the shorter sides instead of running a cable across the 14 ft side.
Thanks again for the info,,,,
