The main panel between the posts has to be wider than any of my clamps

I still did not have enough. I needed to clamp in 4 locations a
distance almost 74", so not even my 6' clamps would work.

I don't use my pipe clamps a lot, but I've got a 3' pipe and a 5' pipe
for each one. That way I can go to 8' without having a lot of extra pipe
when I don't need it. I've only needed the whole length a couple of
times, but it was nice not having to rush out to buy the pipe :-)
