Give a square table or rectangular seating group shade without placing a pole in the middle. This gray offset patio umbrella suspends its 8 x 8-ft square canopy from a side arm, leaving the space beneath open for furniture and movement. The canopy covers 64 sq ft, including the corners that a round canopy of the same span would leave exposed. Rotate the umbrella a full 360 degrees to follow the sun as the day moves on. A double-tier design and top air vent promote airflow and reduce wind pressure, while eight metal ribs support the polyester canopy. The crank lift opens and closes it, and a fixing strap secures the fabric when stored. Overall height is 8 ft, with a 7-ft canopy rim height. A weighted base is required. Color: Gray; Material: Polyester Fabric, Metal; Overall Dimensions: 8 x 8 x 8 ft; canopy rim height 7 ft; Net Weight: 30 Lb; Assembly Required: Assembly Required; Finish: Powder Coated; Manufacturer Warranty: 90 Days; Care: Wipe Clean
