I use this tool to hold my wire weaving mandrels level while I weave wire. The rubber tips hold securely without marring. I even clamp in on over woven sections and it does not leave any damage!

This ring clamp/holder clamps from the outside for filing polishing and stone setting and can also be used to clamp other jewelry.?

Unlike most clamps it can also hold rings from the inside for total circumference polishing and buffing.?

The metal construction of high strength aluminum alloy conducts heat away from the ring. Holds ring sizes 1 Aluminum Ring Clamp / Holder, Hand Hand Held Vise, #1036
