A 9 ft outdoor market patio umbrella spreads shade over a dining table or seating area so you can stay more comfortable on sunny days. The polyester fabric canopy is supported by eight ribs and a 1.5-in diameter iron pole, creating a stable frame for everyday patio use. A crank lift system lets you open and close the canopy in seconds without straining. The push-button tilt function changes the canopy angle to help block low sun, while the top vent allows air to pass through to reduce wind pressure and heat buildup.
