Retainer Rings are generally used with Internal Halyard flagpoles by providing a means of keeping the bottom of the flag close to the pole and as an aid to raise and lower the flag.  Flagpole counterweights (sold separately) are often used in conjunction with these retainer rings.

Retainer rings can also be used on large multi-grommet flags on both External and Internal Halyard flagpoles as a means to keep the flag close to the pole and reduce strain on the upper and lower grommets of the flag.

These beaded retainer rings are constructed of 1" diameter Nylon balls strung onto 1/8" stainless steel aircraft cable with a stainless steel thimble attached to each end with two copper crimps.  Complete with Stainless Steel quick link.

The length of each retainer ring is determined by measuring from the outside of each thimble (the quick link is not included in the measurement).
