Four aluminum posts with a powder-coated metal frame support a retractable yarn-dyed fabric canopy to create a 10 x 13 in shaded area for patios or yards. The rust-resistant frame works with metal feet that have pre-drilled holes so you can bolt the pergola to a solid surface for stability. A rope loop lets you pull the canopy open or closed, while five pulleys on each side guide the fabric along the rails. A locking system secures the closed canopy to maintain your preferred shade position.
