An improved electrical ceiling box including a top portion bounded by a peripheral side portion, with a pair of diametrically opposed ear lugs rigidly secured to the side portion. Each ear lug has a pair of ears integrally formed therewith extending inwardly into the interior cavity of the box. A first ear fits within a recess formed in the bottom edge of the box, while a second ear extends through a slot formed in the side portion of the box. The second ear has a mounting hole formed therein adapted for threaded engagement with a self-tapping screw, while the first ear has a receiving hole formed therethrough for supporting the distal end of the screw. In a preferred embodiment, the box has a substantially hexagonal configuration. In an alternative embodiment, the box has a circular configuration and is shallower, thereby eliminating the need for a pair of slots for receiving the first ears. Preferably, the ear lugs are formed from a heavier gauge material than the remainder of the box for improved strength and resistance to breakage from fatigue.

[ We claim:] [1.] An electrical ceiling box adapted to mount and support a ceiling fan, comprising:a top portion;a side portion rigidly coupled to said top portion and extending substantially normal thereto, forming a box open at one end and defining an interior cavity, said side portion having an exterior surface;a pair of first ears rigidly secured to said side portion and extending inwardly into said interior cavity, each of said first ears having a mounting hole formed therethrough;a pair of second ears rigidly secured to said side portion intermediate said first ears and said top portion and extending inwardly into said interior cavity, each of said second ears having a receiving hole formed therethrough, each of said receiving holes being axially aligned with one of said mounting holes, wherein each of said mounting holes is adapted to threadedly engage a screw for mounting and supporting a ceiling fan thereto, and each of said receiving holes is adapted to allow said screw to extend non-engagingly therethrough, said first and second ears being integrally formed on a pair of ear lugs, each of said ear lugs having one of said first ears and one of said second ears formed thereon, said first and second ears on each of said lugs being spaced a distance from each other and separated by a web thereby supporting said screw at two spaced locations along a length of said screw.
