Crafted for hanging shade this 8 by 8 ft offset patio umbrella delivers 64 sq ft of square shade over outdoor sofas dining sets or hot tubs. Eight heavy-duty metal ribs feed into a thick 2.1 inch metal pole offset to the side so the seating area stays open. Premium polyester resists sun damage and tearing while a top air vent releases pressure. The 360 degree rotation locks at any angle and the weighted cross base accepts two sandbags up to 116 lbs combined to keep the structure anchored.
