Proudly made in the USA, the combination pipe and bench round channel vise is designed to handle the most demanding clamping applications. Unlike most vises that have a fixed center nut, the combination pipe and bench round channel vise nut is anchored at the rear which provides straight line pull and even pressure resulting in greater durability. The round channel design also allows for a completely enclosed spindle and nut assembly keeping debris out and lubrication in for a lifetime of smooth operation. For ultimate versatility, the combination pipe and bench vise is equipped with main jaws, pipe jaws and a machined anvil work surface.
