This 15-foot double-sided market umbrella opens to an 8.85-foot diameter on each side, wide enough to shade a long dining table, a row of pool loungers, or a good chunk of patio at once, while standing roughly 8 feet tall. An anti-UV polyester canopy blocks harmful rays and resists fading, so the dark gray fabric keeps its look through repeated days in the sun. Twelve heavy-duty steel ribs and a rust-free steel pole give the frame the strength to hold up season after season, and a manual crank on the pole lets you open and close the canopy smoothly at your own pace. The toolless assembly goes together in seconds, so you can set it up and reposition it around the yard, terrace, or courtyard without tools. A base is included to keep everything stable and upright. Don't leave the umbrella open during strong wind, heavy rain, or snow, since that's when the canopy and frame are most at risk.
