Double-sided canopy spans 15.4 ft to shade a wide patio dining or seating area, while the 12-rib steel frame supports the polyester fabric panels for stable outdoor coverage. A hand-crank lift on the center pole opens and closes the 9.2-ft wide canopy smoothly so you can adjust shade without moving furniture. The vented top allows air to flow through to reduce wind pressure and heat buildup. Forty-eight integrated LED lights draw power from the solar panel on top to provide soft illumination after dark. An included base can be used with sand bags to help keep the 39-lb umbrella steady in patios, gardens, backyards, or market areas.
