This practical flagpole retainer ring is a helpful assistant for flagpoles and flags. In the internal halyard system, this retainer ring can firmly fix the bottom of the flag close to the flagpole, making the operation of raising and lowering the flag easy and smooth. At the same time, it cleverly reduces the tension on the metal grommets of the flag, avoiding damage caused by frequent friction and pulling, and greatly extending the service life of the flag. When the wind howls, it can effectively support the flagpole and prevent it from deforming due to strong winds. This retainer ring is made of beads with a diameter of 0.98 in. The beads are hung on a sturdy steel aircraft cable, and both ends are looped around stainless steel and reinforced with aluminum or copper. It is extremely convenient to install. You can complete the installation by hand without the need for any other tools. The equipped stainless steel hook quick links can easily connect all parts tightly together. Its size is suitable for flagpoles with a diameter of 2 to 3 in. Before purchasing, you only need to measure the diameter at the base of the flagpole to select the appropriate specification.
