This is only a shade cover for your existing pergola or shade structure. No poles, frames or structures are included. Please send us a message if you have any questions. The sizes listed are the size of the shade cover, not the size of your pergola. If you have a 10×10 pergola and you want the cover to hang down 3 ft on each side (can be slid back and forth so it hangs farther down on one side), you may need a 16×9. Please measure where the cover will sit on your pergola before ordering. We can make custom sizes if you don’t see what you need, just ask. We are here to help. 200GSM lock-stitch knitted polyethylene shade fabric that blocks up to 90% of harmful UV rays and can reduce ambient temperatures by up to 30%. The perfect balance between visibility, sun blockage, air & water flow. Slightly opaque, lets light through so you’re not in the dark. 2 inch rod pockets (rods not included) for extra stability. Simply insert weighted rods (from the hardware store) for extra stability in wind. Will not allow water to pool and sit on top like waterproof covers do. Rod pockets are located on the width “W” (the second size listed in the sizing chart). On a 16L x 8W, the rods are on the 8ft ends. Allows breezes to pass through the mesh so that hot air is not trapped, but cuts down on gusty wind on patios and can slow down rain water. High strength monofilament thread, tear resistant, does not absorb water or allow mildew/mold to grow. An affordable and much more attractive option than tarps for providing shade and privacy while allowing air and water passage. Easy to clean with dish soap and a soft brush and easy to install, adjust or remove during winter. Trusted Alion Home Brand quality and value. If you need a size you don’t see listed, a different color, special grommet placement or have questions about which product is best for you, please contact our friendly customer service team. 1 Rod Pocket Shade Panel (Rods are not included).
