This fabric screen helps you beat the heat by providing effective sun protection in back yards or on decks and patios, without needing a freestanding umbrella or waiting for your shade trees to grow. To provide strength and durability for seasons of use, it is made to our specifications from dense-knit (300g/m²) polyethylene fabric that blocks 90% of the sun’s UV rays, with reinforced stitching and UV, mold and mildew inhibitors. Secured with the included heavy-gauge 316 stainless-steel hardware, the permeable screen allows wind and rain to pass through, minimizing strain on the fittings and preventing water from accumulating on top. (We recommend storing the screen during the off season and in extreme weather conditions.) Measures 11’10” (3.6m) square. Backed by a 10-year UV protection warranty. Installation instructions included.
