Double-tier polyester canopy and metal ribs span a 9 x 8 in frame to create expansive shade for patio dining or poolside seating. The vented top lets air escape to reduce wind pressure, while the tilt function helps you keep the shaded area aligned with the moving sun across the day. A crank handle raises and lowers the canopy so you can open or close the umbrella with minimal effort. Two included sandbags wrap around the pole to add stability, and a fixing strap keeps the canopy neatly secured when not in use.
