ABSTRACT:
Disclosed is an electrical tool for removing knockouts from electrical boxes. The tool includes a first arm and a second arm each comprising a handle, a jaw, and a recess joining the handle and the jaw. A pivot pin rotatably joins the first and second arms while an elongated slot allows the second arm to slide along the slot relative to the first arm. The first jaw includes two projections to be placed on one side of an electrical box wall. The second jaw includes a projection which is placed within the circumference of a knockout. Serrated projections which extend from the end of the first and second handles can grip the knockout and remove the knockout from the electrical box wall.
