A circle of fade- and mildew-resistant Sunbrella acrylic in sapphire blue supported by a sleek black powdercoated frame blocks out 98% of the sun's UV rays. Simply turn the collar on the pole to access the easy-tilt feature that allows you to follow the sun all day. The frame's smooth-turning crank opens and closes the umbrella. The 9' Round Sunbrella Sapphire Canopy with Black Round Tilt Umbrella Frame is a Crate and Barrel exclusive.
