Garden Winds 13 FT - Umbrella Canopy Replacement - Green REPLACEMENT CANOPY ONLY. METAL STRUCTURE NOT INCLUDED. Please measure the rib of your umbrella! Our replacement canopy can accommodate a 78-inch umbrella rib, with a +/- 1 inch variance at most. This replacement canopy will fit most standard 13 ft. patio market umbrellas with a 8-rib design. Due to the sheer number of umbrellas produced by different manufacturers, we cannot guarantee that our canopy will fit your frame.
