This is the patio umbrella that provides constant shade from sunrise to sunset because it can pivot laterally using its cantilevered arm, and tilt to a full 90°. Its 10' diameter octagonal canopy is made of durable 100% polyester fabric that resists UV fading and weathering, and provides 78' sq. of shade, protecting you and guests longer than other umbrellas that cannot pivot or tilt. The canopy can be opened and closed using a hand-crank that requires minimal effort, and an easy-to-turn locking brace that attaches to the main support maintains the position of the canopy. The canopy is supported by eight adonized aluminum ribs that keep the canopy taut. The cross arm stand can be secured with four block weights (not included). Includes storage cover. 102" H x 10' Diam. (40 lbs.)
