Abstract: A clamp for straightening an automobile body or frame which includes two gripping members which permits attaching a pull chain in such a manner that the gripping members may be pulled in any desired direction without repositioning the gripping members. The gripping members are rectangular plates bolted to opposite sides of the automobile body or frame. A clevis may extend above one plate so that a link of the pull chain can be attached by a clevis pin. Alternatively, gripping member may have one or more D-shaped lops extending normal to the plate, while the other gripping member has at least one loop extending from an end of the plate and at least one loop extending laterally from a side of the plate.
