ABSTRACT:
A method of manufacturing a sizing ring adapted to accurately fit an individual for a recloseable ring. The method includes: providing a generally arcuate member and having first and second ends; forming a segment of reduced cross sectional area along the generally arcuate member to form a living hinge therein and to define first and second shank portions; and configuring the first and second ends to form a connector such that the sizing ring is a one piece polymer member configured for movement between an open position, in which the sizing ring is adapted to be positioned over a portion of an appendage without sliding over a length of the appendage, and a closed position, in which the sizing ring is adapted to form a band around the appendage and has an inner surface that is generally circular to correspond to an associated ring size.
