US Patent 9667049 Electrical box assembly for poured concrete floors

An electrical box assembly for concrete pours. The electrical box assembly includes an electrical box with a sidewall defining an electrical enclosure and a leveling ring for accepting the mounting of an electrical component to the box. Mounting bosses within the electrical box extend longitudinally along the inner surface of the sidewall and facilitate a means for mounting the leveling ring to the electrical box. The leveling ring includes a flange that is adapted to overlap the top rim of the electrical box. Component attachment arms on the leveling ring enable mounting of an electrical component to the electrical box assembly. Cover attachment arms on the leveling ring facilitate mounting of an electrical cover to the electrical box assembly. The electrical box assembly eliminates the need for clips and adhesive for leveling an electrical component with respect to the surface of a concrete poured surface.
