Our newest and best ring clamp offers the user greater reliability than other ring clamps. The 'collar' feature incorporated into the design allows the user to station it in the v-cut of a bench pin for greater stability and less effort. This clamp is slightly smaller in diameter and fits perfectly into our BPN-106.50 custom mahogany bench pin. Features include thick leather jaws and a thick brass band with metal axle. Made of red Philippine straight-grained mahogany.
