Jelinek Cork understands the importance of uniformed quality that custom rod builders demand and therefore ring quality is very carefully selected and segregated to meet these strict standards. Various ring qualities, known as Flor, Super, and First, are offered by Jelinek.
The most common ring sizes are 1-1/4" diameter by 1/2" thickness and 1-1/2"
diameter by 1/2" thickness. Most sizes and styles are produced either with or
without a center hole (the center hole is usually1/4").
