Double-sided canopy design stretches across a long outdoor seating area to shade a dining table or several lounge chairs at once. The polyester fabric canopy helps block direct sun, while top vents let warm air escape and breezes pass through for better air circulation. A steel frame with a 1.9-in diameter pole supports the 26-lb umbrella for regular patio use. The hand-crank system makes opening and closing the 15.4-ft wide umbrella straightforward, and a weighted base is required and sold separately.
