Abstract
A device for use in applying panels to a wall, for providing holes in the panels to expose electrical outlets and switches therethrough. The device includes two components, a box and a cutter plate; the box is fitted to an outlet or switch, that is in position in the wall, and has pins and a peripheral cutting edge directed outwardly when the box is so fitted. The wall panel to be put on the wall is tentatively set in place, bearing against the pins, and is then tapped to drive the pins into and through the panel. The panel is then removed from such tentative position, carrying the box with it, by means of the pins friction-holding in the holes, and laid on the floor with the box down. The cutter plate is then fitted on the pins which are exposed through the panel, applied to the upper surface of the panel, and struck with a hammer, forcing the panel against the peripheral cutting edge of the box, cutting through the panel and leaving a hole therein of the size, shape and location of the box.
