Abstract
A double-single stainless steel electrical junction box is configured to receive two single covers. A center bridge spans between the top and bottom surfaces to define a first and a second cover plate-mounting aperture adjacent each lateral side of the bridge. The interior compartment of the junction box is common to both of the first and second cover plate-mounting apertures. Electrical conduit hubs can be disposed above the top surface and below the bottom surface of the junction box to allow electrical wiring to reach the interior compartment.
Claims20
A stainless steel double-single electrical junction box, comprising:
- a rectangular box defined by:
- opposing side walls oriented parallel to each other:
- a top wall and a bottom wall opposing the top wall, oriented parallel to the top wall and spanning between the opposing side walls;
- and
- a rear wall oriented perpendicular to the top, bottom and side walls, the rear wall spanning between the opposing side walls and between the top wall and the bottom wall,
- wherein the rear wall, the top wall, the bottom wall and the opposing side walls together define an interior compartment with an open front side opposite the rear wall;
- a vertically-oriented center bridge spanning between the top wall and the bottom wall, the center bridge disposed adjacent the front side, and defining:
- a first cover plate mounting aperture horizontally between a first of the opposing side walls and the center bridge;
- and
- a second cover plate mounting aperture horizontally between the center bridge and a second of the opposing side walls,
- wherein the interior compartment is open and common to both of the first and second cover plate mounting apertures,
- wherein the center bridge does not create a partition in the interior compartment, and
- wherein each of the first and second cover plate mounting apertures has identical dimensions.
A system for mounting multiple single cover plates to a stainless steel electrical junction box, the system comprising:
- a rectangular stainless steel box comprising:
- opposing side walls oriented parallel to each other:
- a top wall and a bottom wall opposing the top wall, oriented parallel to the top wall and spanning between the opposing side walls;
- and
- a rear wall oriented perpendicular to the top, bottom and side walls, the rear wall spanning between the opposing side walls and between the top wall and the bottom wall,
- wherein the rear wall, the top wall, the bottom wall and the opposing side walls together define an interior compartment with an open front side opposite the rear wall;
- a vertically-oriented center bridge spanning between the top wall and the bottom wall, the center bridge disposed adjacent the front surface, and defining:
- a first cover plate mounting aperture horizontally between a first of the opposing side walls and the center bridge;
- and
- a second cover plate mounting aperture horizontally between the center bridge and a second of the opposing side walls,
- wherein the interior compartment is open and common to both of the first and second cover plate mounting apertures,
- wherein the center bridge does not create a partition in the interior compartment, and
- wherein the center bridge comprises a channel that is recessed rearward from the front side.
