Anchor a year-round focal point on your patio with this 12 x 10-foot aluminum pergola featuring a smoothly retractable canopy that glides on ten pulleys. Thick 3.2 in x 3.2 in powder-coated aluminum columns resist rust and chipping, while pre-drilled anchoring plates and eight metal stakes offer flexible installation. The polyester canopy filters sunlight when extended and retracts fully for an open-sky experience.
