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 EZ ZipBlockers 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 tubes and the top portion can stay in the tube for storage. The insert slides into the awning roller and rolls up with the awning. This allows you to reach the zipper without a ladder. When you set up again, simply zip the body panel into the insert.
