Built around a powder-coated metal frame with eight heavy-duty ribs, this 8.5-foot umbrella holds a 160-gram polyester canopy that resists sun and wear over a long season outdoors. The crank handle opens and closes the shade quickly, and a spring button joins the two pole sections during setup. An air vent at the top promotes circulation and improves stability when a breeze picks up, while protective rib pockets keep each rib seated. Overall dimensions are 8.5 by 8.5 by 7.4 feet with a 6.2-foot rim height and a 1.2-inch pole, and net weight is 9.5 pounds. A separate umbrella base is required. Assembly needed.
