The 360° rotating anti-wrap ring design and upgraded built-in screw allow the flag to fly freely even on windy days. The rotating ring is made of stainless steel, and other parts are crafted from high-quality aviation-grade aluminum alloy for durability and adaptability to various weather conditions. The curved design of the small ring minimizes wear and tear. It uses two screws for adjustment; the long screw fits 0.75 in. diameter flagpoles, and the short one fits 1 in. diameter flagpoles, compatible with flagpoles ranging from 0.75 to 1.02 in. diameter. Installation is simple: select the appropriate screw based on the flagpole diameter, slide the screw into the flagpole, tighten the wing nut, and then attach the flag.
