Abstract: A tool to reduce the rotational force on a pipe to be held in a chain vise includes a curvilinear or inverted V-shaped base which saddles the pipe to be held. A U-shaped frame is mounted to the base such that one or more roller bearings may be mounted between the opposing sides of the U-shaped frame. The roller bearings provide a bearing surface for the chain of the chain vise, allowing the chain to be tensioned without applying torque to the pipe to be held. A pair of the tools may be spaced apart upon the periphery of a large pipe with the chain passing over the roller bearings of each tool.
