ABSTRACT:
A tool for bending metal wire hangers such as those used for hanging false ceilings below exposed under floor structures of the type separating successive floors in modern multiple story commercial buildings and in other buildings where a lowered ceiling is desired. The wire bending tool includes a pair of operating handles connected to a gripping jaw having members for holding a wire to be bent. The gripping jaw forms part of a rectangular block to which a third handle is pivotally mounted. The third handle is associated with a roller which cooperates with two corners of the block to bend the wire into two successive right angles as a third handle is pivoted about its axial connection on the rectangular block.
