Double-side canopies on this 15.4 x 9.2 x 8 in twin patio umbrella create an extra-large shade area for outdoor dining or seating. A hand-crank system on the 1.9-in diameter steel pole lets you smoothly open and close the canopy to adjust coverage as the sun moves. The 12-rib metal structure supports the polyester fabric while a vented top allows air to circulate and helps reduce wind pressure. Forty-eight solar LED lights draw power from the top solar panel and standby battery to provide illumination after dark. A weighted base is necessary for stability and is sold separately.
