I cannot tell you how many different awning poles we have tried, and tossed out — wooden dowels, fiberglass battens, stainless steel and aluminum tubing. We even tried aluminum rod. Every one of these awning poles bent, broke or shattered in a gust of wind at one time or another.
BUT, here is what we found! My husband, Andy, was a rigger. He installed many roller-furling systems. We had a stack of roller furling foils left over from many headstays that were shorter than what the furling system supplied in foils.
