As of last week I set up my 12' wide by 30' long tomato tunnel. It's a well designed concept and very strong as it's constructed out of 1 3/8" galvanized pipe rail used for chain link fencing. I purchased the 'high tunnel bender' through Johnny's Selected Seeds last year along with an assortment of specialty brackets. The brackets are designed to attach the ridge pipe and purlins to the arches and tie the whole structure together. I am using the ridge pipe and the purlins to trellis my tomatoes up a string line. The frame is covered with 6mm poly and held onto the frame with a light duty synthetic rope and laced over and back along the length of the frame. The rope is held into place with 6" carriage bolts bent at 45* angle at the base of each footing in which the arch is slotted into.
