What is the diameter of the pole? I want to velcro a flag at the top so I need the measurement. thanks!

I think it is 11 feet but not sure, we sent it back because not all the pieces came in delivery.

I received mine, but it didnt have any bolts or the peg to put the weight on! Can there be a credit issued? I had to buy bolts and a wood dowel

Same happened to me, I sent every thing back and got my money back.

What is the size of the box(es) that will be used to deliver this item?

It has been some time since I ordered them; however, I believe that one box is 48" x 12" x 3" as an estimate.

What is the maximum jump height that can be measured? Also, what is the interval between slats (i.e. 1/2 in, 1 in, etc.)?

*Telescopes from 4 to 12 feet, with heavy duty base and casters for stability and portability*Moveable metal arms placed at 1" increments allow for accurate jump measurement
