This is a universal umbrella canopy. This canopy has been designed to provide a general fit, not a custom fit, for most patio umbrellas. Rejuvenate the look of your patio umbrella. Our 10 ft. universal umbrella canopy replacement will fit most standard 10 ft. market patio umbrellas. Why you want to choose our cover: We used double strong thread to sew each line. Our workmanship is much better and stronger than those who are using much thinner thread to produce the cover. We had used the 220D Polyester fabric (fade resistant, UV 30+) on all of our cover which is very thick and strong. Unlike many of the 180g Polyester cover you see in the market. The fabric are much thinner and easy to break when you pull. We value your business and we want to bring you a product that have great "VALUE" and " QUALITY " at the same time.
