Double-sided patio umbrella creates a wide shade area with a 13-ft x 7-ft outer canopy supported by 5+2+5 metal ribs to help reduce shaking in use. Polyester fabric canopy is water-resistant, sun-proof and wear-resistant for outdoor seating or dining. A smooth crank handle lets you open or close the 6.6 x 7.6ft frame with minimal effort, while a 2-level adjustable locking pin helps hold the canopy height. The included 29 x 29 x 5 in weighted base offers 135-lb filling capacity to enhance overall stability on your patio.
