Built to cover oversized outdoor gathering spaces, this 15 ft twin market umbrella offers roughly 135 sq ft of shading from a single center pole. The polyester canopy resists fading and light rain while three integrated air vents allow breezes to pass through without lifting the fabric. Twelve enhanced steel ribs keep the canopies rigid, and a side-mounted hand crank raises both panels at the same time. A weighted base is recommended and sold separately for windy locations.
