Weighted Rods: The pergola canopy cover is equipped with weighted rods which help to hold down the canopy in high winds. Each end of the weighted rod has a finial for tie-downs. You can keep the rods in place if using tie-downs. UV Blocking: Made from high-density polyethylene and blocks up to 95% UV rays. The canopy shade cloth provides good privacy and blocks out the scorching sunlight, creating a cozy environment this summer. Permeable: The breathable fabric allows rain and air to pass through, rather than gathering a puddle on the top or catching the wind. Provide a 3-year limited warranty under normal weather and use. Easy to Install: 2 edges are finished with rod pockets. Just screw the rod sections together and insert the assembled rod into the rod pocket to hold down the canopy. Please note: pergola shade canopy only. A Pergola frame is not included. Applications: Shade cloth protects your garden, backyard, porch, pergola, balcony, deck, and swimming pool. Reduce the temperature of shaded areas and provide privacy protection.
