X marks the spot with Canopies and Tarps' 3/4" X-shape fittings for specialty roof structures, just one of the many offerings at our one-stop shopping site. Each X-shape fitting is cast from durable, galvanized steel material to ensure that everything stays in one place and your inventory is safe from bad weather. The thick eyebolts add yet another level of stability by securing each pole in place. The fitting's inside diameter is 1", so make sure your poles will fit before purchasing.
