Abstract: An electrical connector box adapted to be used in connection with the raised floor concept with a raised floor positioned above the main floor. A plurality of substantially rectangular openings are formed in the raised floor. A frame is positioned in the openings. The electrical connector box is lowered into engagement with the frame and into the space between the raised floor and the main floor. The electrical connector unit includes flange means which is adapted to rest adjacent the raised floor to suspend the electrical connector unit between the floors. The unit further includes flange means engaging the under-surface of the raised floor to maintain the unit in position. A sling or saddle-like structure extends downwardly from the electrical connector box into the space between the raised floor and is adapted to receive wires, cables and the like. There is a hinged top plate movable to a first position providing access to the interior of the electrical connector box and a second closed position.
