Flagpole Beaded Retainer Rings (also known as Beaded Retainer Slings) 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.
Retainer rings can also be used on large multi-grommet flags on both external and internal halyard flagpoles as a means to keep the flags close to the pole and reduce the strain on the upper and lower grommets of the flag.
These beaded rings are constructed of either 1" or combination of 1" & 2" 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.
Standard stock colors are White, Silver and Bronze #313., and Black
The length of each retainer ring is determined by measuring from the outside tip of each thimble (the quick link was not included in the measurement).
