Abstract: An improved electrical outlet box having thin wall construction and localized elements for structurally reinforcing the box. The thin wall outlet box includes a bottom wall and a perimeter wall perimetrically bounding the bottom wall and an open upper end defined by a lip. The perimeter wall comprises a plurality of sidewalls which join together to form corners. Each of the sidewalls has a reinforcement rib longitudinally extending substantially parallel to the lip and projecting inwardly toward the interior of the box. In addition, each of the corners has an outwardly projecting rib which extends downwardly from a point on the corner between the lip and the bottom wall onto the bottom wall.

Abstract: An improved electrical outlet box assembly includes an outlet box and a cover. The outlet box includes a bottom wall and a sidewall perimetrically bounding the bottom wall and an open upper end. The sidewall supports a pair of diametrically opposed ear lugs. Each ear lug has a pair of ears integrally formed therewith extending inwardly into the interior of the box. The ears secure a fastening element. The cover is removably frictionally engagable with the box and provides a closure for the open upper end of the box. The cover includes a generally planar surface with a pair of diametrically opposed dome-shaped protrusions extending from the top surface of the cover. The protrusions are positioned on the cover such that they align with the ears and accommodate the fastening elements therein. The cover further includes a pair of locking members extending from the bottom surface of the cover and which are frictionally engagable with the ears thereby holding the cover onto the outlet box.

Abstract: A protective housing for electrical outlets and the like includes a box surrounding the outlets and a cover. A gasketless joint is formed between the hinged cover and the box for inhibiting entry of moisture into the box. The box includes a slot in its peripheral wall for receiving a cord with a plug that is positioned inside the box.

Abstract: A mounting assembly is attachable to a pre-manufactured electrical box. The box which includes a pair of opposed side walls, is insertable into an opening cut into a mounting wall. A pair of clip-on securement members are mountable onto each of the opposed side walls. Each securement member includes a bracket positioned on an external surface of the side wall and a brace supported by the bracket. The brace is movable on the bracket so as to clamp the box to the mounting wall.

Abstract: A bracket supports an electrical access floor module in an opening in a raised floor. The bracket includes an elongate member having a first surface positionable on the upper surface of the floor, and a second surface extending perpendicular thereto into the floor opening. The second surface of the bracket includes a pair of bendable legs adapted to be bent under the floor to lie along the under surface of the floor. This securely supports the bracket in the floor opening. The second surface of the bracket further includes a screw receiving member for accommodating a screw inserted from within the access floor module to secure the module in the opening. The screw accommodating member prevents relative lateral movement of said access floor module with respect to said opening.

Abstract: A circular inner knockout and a non-circular outer knockout formed in a wall are individually connected to the wall by frangible webs located opposite from one another. The frangible web connecting the inner knockout to the wall is stronger than the frangible web connecting the outer knockout to the wall. The periphery of the outer knockout includes by a plurality of interconnected discrete circular curved portions, and does not completely surround the inner knockout.
