Retainer rings are generally used with internal halyard flagpoles. These rings provide a means of keeping the bottom of the flag close to the pole, and helps aid in raising and lowering the flag.
Retainer rings can also be used on large multi-grommet flags- on both external and internal halyard flagpoles. In this instance, the Retainer rings act as a means to keep the flag close to the pole and reduce the strain on the upper and lower grommets of the flag.
These beaded retainer 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.
