This beaded retainer ring is constructed with 1" diameter nylon balls that have been strung onto 1/8" stainless steel aircraft cable with a stainless steel thimble attached to each end with copper crimps. These come complete with a stainless steel quick link. Length of this retainer ring is 42" which is determined by measuring from the outside tip of each thimble. Retainer rings are used to keep the bottom of the flag close to the pole and as an aid in raising and lowering the flag. They also come in handy when using with a multi grommet flag to keep the flag close to the pole and limit the strain placed on the flag.
