Created with 100% solution-dyed Sunbrella® or Sattler awning-grade acrylic fabrics, our umbrellas provide the highest performance in the harshest climates with superior water resistance and durability. This 5.5′ square crank-to-lift auto-tilt fiberglass rib market umbrella features a durable powder-coated aluminum center pole with commercial-grade 1/2-inch diameter fiberglass ribs that remain flexible in high winds and resist bending or breaking. Raising and lowering your umbrella is a breeze thanks to the crank-to-lift feature. To engage the tilt mechanism, simply turn the crank to lift and open the canopy. Once fully open, continue to turn the crank and the canopy will automatically tilt, up to 30 degrees. Market-style umbrellas include a top vent with the option to add a valance or a double top vent.
