Cost effective, chic, flawlessly designed and versatile, the ALEKO® Triangle Shade Sail is a beautiful addition to any patio, backyard, pool, or other outdoor area. Shade sails are a clever alternative to pergolas, covered porches, and awnings - their simple design makes them easy to install wherever needed; anchor to houses, fences, trees, or freestanding columns. Whether you suspend the sail for a floating effect or anchor it to wood or steel columns for a more enclosed feeling, the built-in steel D-rings at each corner are strong enough to keep the sail's form. The perimeter of each sail is designed with a gentle catenary curve that controls the fabric tension. When tensioned properly, the sail will not wrinkle, sag, or flap in the wind. Reinforced webbing around the perimeter also ensures the longevity of this product. The unique, high-density polyester mesh fabric provides cool shade, protection from UV radiation and can withstand prolonged exposure to moisture and temperature extremes without growing mold or mildew. Care for your sun shade by washing it with regular soap and water by hand, or machine wash it around 100 degrees Fahrenheit. An installation kit is not included with this shade sail, however a complete kit can be purchased from the ALEKO® website here.
