Portable chain vises set up on a level, flat, solid floor wherever they're needed for pipe threading, cutting, and welding. Their base provides a stable footing to resist tipping. They tighten their chain around pipe to lock it down and prevent rolling or shifting. The chain holds irregularly-shaped materials that might be unstable in a yoke vise or V-head stand. A pipe rest at the back of the vise supports pipe along its length. Additional support may be required for long pipes.

These parts replace old or broken components to maintain the performance of pipe stands and vises. They fit specific pipe stand and vise brands and models.
