Anti-wrap design: the flag pole rings are designed with a 360-degree rotating anti-wrap ring, allowing flags to fly freely in the direction of the wind and preventing the flag from wrapping around the flagpole. Material and size: our flag pole rings are made of aluminum alloy, durable and rust-resistant for long-term use. The inner diameter of the ring is 1 inch, compatible with 1-inch diameter flagpoles. Please measure your flagpole diameter carefully. Easy to install: simply attach the 4 aluminum alloy mounting rings to the flagpole, then connect the top and bottom grommets of the flag to the clip hooks on the rings, and adjust the position as needed. Included components: the set includes 4 clip hooks to securely connect the flagpole rings to the flag grommets, ensuring easy attachment and stable performance.
