Shade all of the area under your awning! Don't put up with the heat and glare of early morning or late afternoon sun. The SunBlocker's weather resistant open-weave fabric cuts almost 85 Percent of light to keep you cool and comfortable - but it doesn't block your view! Fabric construction is a woven 100 Percent polyester with a durable vinyl coating. It slips quickly and easily into the open slot on most awning roller bars. Grommets and ground stakes included.
