Abstract:

An electrical junction and outlet box is formed from a side wall fabricated from an elongated flat strip bent into a desired geometric shape, with its ends joined together by means of a dovetail joint which is appropriately staked to make for a tight joint. A bottom for the box is formed by a flat plate shaped in the same geometric shape as the side wall. The side wall and bottom plate have alternate lip and indented portions formed around their edges, the lip portions of each of these members fitting within the indented portions of the other. The bottom plate has projections formed along the edges of the inner surfaces of the indented portions thereof which facilitate the location of the bottom plate against the bottom edge of the side wall immediately prior to welding. Mating projections on the side wall and the bottom plate appear opposite each other to form weld points for joining the side wall and the bottom plate together. The box further has a pair of ears with apertures formed therein for receiving mounting screws, these apertures being dished at their entrances to facilitate the reception of the screws therein.
