Can also be used for sunshade panels, drapes and curtains.The inside dameter of the ends(eye bolts) is 1/2 in, and it cannot fit the guide poles of other steel pergolas. We sell rods with big eye bolts(1.2''+ dameter of the hole ASIN B0D19JBM6M) seperately. WEIGHT – The weight of the rods for a pergola cover is important and our rods weigh more than the industry standard. They hold the cover down and make it easily adjustable when needed. END EYE LOOPS – At the end of each rod is an eye loop to allow you to secure the rod/pergola cover to the structure. This will help prevent the cover from swaying during windy days.
