This patio umbrella features a 9 foot hexagonal canopy made of Olefin fabric and a powder-coated aluminum two piece 1 1/2" pole. The fiberglass ribs and molded nylon joints, hubs and end tips create sturdy structure. The easy to use crank lift makes opening and closing easy to do. Incredible strength and flexibility to absorb strong wind and abuse. Base shown in photo is not included.
