This flagpole retainer ring is suitable for the internal rope system. It can fix the bottom of the flag to the flagpole as much as possible, making it convenient to raise and lower the flag. By leaning the flag against the flagpole, it can prevent the flag from deforming in strong winds. By reducing the tension on the flag grommets, it helps to extend the service life of the flag.

Its length adjustment is simple to operate. It is equipped with an adjustment link ring system. Without any tools, you can easily adjust the length of the cable through the friction grip of the cable. This flagpole counterweight ring weighs 1 lbs. and can also be used as a counterweight. Whether it is on an internal or external rope flagpole, it can keep the flag close to the flagpole. It is suitable for flagpoles with a diameter of 6 in. 7 in. 8 in. 9 in. 10 in. 11 in. and 12 in.
