ABSTRACT:
A tool for prying open punch-outs from an electrical box. The tool includes a handle member, an elongated shaft which extends outwardly from the handle member and terminates in a bent tip, and a slide assembly mounted to said elongated shaft. The slide assembly is adapted to engage a lip which extends perpendicularly from a wall of the box. The bent tip of the elongated shaft is adapted to act as a cam in order to pry open a punch-out from the box when the slide assembly engages the perpendicularly extending lip and the handle is rotated.
