Hey Bernie, check out the Haygrove high tunnels... folks are indeed putting acres of crops under cover with them. Cut flowers, tomatoes, cherry orchards...

The clips are aluminun, so they hold a screw, because indeed if this was all that held the sucker together, it wouldn't last a day in our winds. LOL The top clips are also screwed with a Tek screw into the frame.

But here's the part that really holds things one... and it's kind of a stinky one. After installing the ribbon board, more channel is screwed onto the tops of the end arches. And the channel is straight and though aluminum, isn't all that fond of bending. So clamps, vice grips, what-have-you will definitely be needed to hold the channel in place while you stand in all kinds of awkward positions on a ladder to screw more Tek screws into hardened conduit. }=oP

So this is a pic of a piece of channel clamped down to be screwed.
