A light but solid powder-coated aluminum frame resists breakdown for greater longevity..ADJUSTABLE CANOPY: This manually retractable awning features a 58.5" long hand crank that opens the awning smoothly and quietly, and is easily adjustable to provide you with better shading according to different sunshine exposure and a certain level of privacy..LOWER HEAT LEVELS: The patio awning is made of 280g polyester and PU coating fabric, protects your exterior from the sun's damaging UV rays, and effectively reduces the heat inside your home, all while possibly lowering your cooling bill..VARIETY OF SURFACES: Our door canopy can be attached to various surfaces such as concrete, solid brick wall, and even on a wooden wall, on any door, balcony patio, or window. All hardware included for attachment to concrete surfaces..CANOPY DIMENSIONS: Shaded Area: 104 ft². (You will need to measure up the wall to where you'd like the awning – at least 8.2' - 11.5'.
