Built to throw shade across larger gatherings this 15 ft double-sided patio umbrella spreads a twin canopy over two seating zones at once. Premium 180g polyester resists fading and beads off light rain while twelve heavy-duty ribs hold the umbrella steady. Thickened powder-coated steel pipes resist corrosion through the summer season. A wide cross metal base with sandbag pockets supports up to 180 lbs of ballast and the smooth hand crank opens and closes the dual canopy in one motion.
