Use the same fittings to make sizes (widths) from 4’ all the way up to 30’. The length of the structure can be as long as the available tarps sizes.

Our pipe size is standard top rail fence material with an outside diameter of 1-3/8 “ . You can purchase this size at most hardware supply stores and fence supply yards. If you don’t want to do your own cutting I recommend a fence supply yard. Most will cut your pipe to size for a nominal fee. Sometimes for no charge at all.
