An assembly includes a structural member or frame that supports a load. The frame has a rectangular opening therein to a cavity within the frame that is adapted to house electrical components therein. There are a plurality of opening screw holes in the frame and spaced apart completely around and outside of the opening. The mining apparatus also includes a cover for the opening, the cover including a plate with an area larger than the opening, the plate having a first surface and an opposite second surface. The cover also includes a lip protruding from the second surface, the lip extending over and around and enclosing an area of the second surface and defining a protrusion that, when the cover is laid over the opening, fits closely within the opening.

The invention claimed is: 1. An assembly including a structural member that supports a load, said structural member having an opening therein to a cavity within said structural member that is adapted to house electrical components therein, said structural member opening being defined by a perimeter
The invention claimed is: 1. An assembly including a structural member that supports a load, said structural member having an opening therein to a cavity within said structural member that is adapted to house electrical components therein, said structural member opening being defined by a perimeter surface, and a plurality of opening holes in said structural member and spaced apart completely around and outside of said opening, a cover for said opening, said cover including a plate with an area larger than said opening, said plate having a first surface and an opposite second surface, a lip attached to and protruding from said second surface, said lip extending around and enclosing an area of said second surface and defining a protrusion that, when said cover is laid over said opening, fits closely within said opening, said protrusion having a surface that lies adjacent and parallel to the entirety of said opening surface, and a plurality of plate holes, in said plate and spaced apart completely around and outside of said opening when said cover is laid over said opening, and a plurality of means for attaching the cover to the structural member, with each attaching means received in a respective one of said plate holes and received in a respective one of said member holes so that said attaching means is on the first surface of said plate. 2. An assembly in accordance with claim 1 wherein said opening is rectangular. 3. An assembly including a structural member that supports a load, said structural member having a rectangular opening therein to a cavity within said structural member that is adapted to house electrical components therein, said structural member opening being defined by a perimeter surface, and a plurality of opening screw holes in said structural member and spaced apart completely around and outside of said opening, a cover for said opening, said cover including a plate with an area larger than said opening, said plate having a first surface and an opposite second surface, a lip attached to and protruding from said second surface, said lip extending over and around and enclosing an area of said second surface and defining a protrusion that, when said cover is laid over said opening, fits closely within said opening, said protrusion having a surface that lies adjacent and parallel to the entirety of said perimeter surface, and a plurality of plate screw holes, in said plate and spaced apart completely around and outside of said opening when said cover is laid over said opening, and a plurality of screws, each screw having a head, with each screw received in a respective one of said plate screw holes and received in a respective one of said member screw holes so that the head of said screw is on the first surface of said plate.
