Natural Cork Rings are most commonly used by Custom Rod Builders, and can be presented in various sizes. The most popular rings are with ½” (12,7 mm) high, although currently in Europe, ¼” (6,3 mm) high is becoming preferable. Diameter with 1 ¼” (31,8 mm) is the regular size, but any diameter can be produced, accordingly with customer’s needs.
Natural Cork Rings can be supplied in Flor Grade (in very small quantities); Super Grade and “A” Grade. “AB” and “B” grade are seldom asked by customers. Following customers needs, there is nowadays a quite large of other special cork rings: Rubbercork Rings; Burl Cork Rings; Burnt Cork Rings; Copano Cork Rings.
