Outdoor pergola canopy shade cover creates a cooler area by blocking much of the harsh sunlight over your seating, pool, playground or porch. The polyester cover measures 17 x 7 in and is made of durable cloth that resists wear and tearing for repeated summer use. Reinforced stitched edges and corners improve strength while copper grommets at the corners help water drain instead of pooling. Four straps secure the canopy tightly to your pergola frame so it stays in place in hot weather.
