ABSTRACT:
A multi-directional pull tool has a fist-like cylindrical end section from which a elongated boxed shaped second section extends. The tool is designed to attach to the square or rectangular opening at the end of a damaged frame rail. The tool is attached directly to the sidewalls of the frame rail, allowing for a more direct pull of the infrastructure of the frame rail in the opposite direction in which it was hit, thus allowing a cleaner pull and a setting of the control points of the frame rail back in line. The elongated second section comprises a plurality of openings along the length of the section, through which pull chains, via clamps are connected. In this manner, the damaged frame rail can be pulled in the multitude of directions necessary to return the rail to the proper position without the need to change or reposition the clamps and other pulling equipment.
