Tip for assembling the 7ft My First Trampoline with enclosure.

I ran into what seems to be a problem many people have when assembling the trampoline enclosure.
The holes will not line up on the arches if the bottom pipe (#11 on instructions) is facing the wrong way. However the instructions do not specify that they are directional and there is not a clear way to know if it is facing the right or wrong way.
Good luck.
