This Premium Razor Sail Sign is built to move in the wind, making it truly hard to miss! Measuring 17' tall, this flag is made of super poly knit fabric and can showcase dye sublimated graphics on both sides. The flag attaches to a fixed hook using a bungee cord and features include nylon webbing pole pockets, uniform carbon composite overlay pole construction with high-gloss black paint finish, polished aluminum collar pole segment ends and ergonomic, rubber-reinforced base grip. The ground spike is constructed of chrome-plated steel with nylon polymer bearing cover. There is a lifetime warranty on hardware; one-year warranty on ground spike.
