ABSTRACT:
This patent discloses a floor box for a service distribution system in a concrete floor slab. The floor box has a bottom, end walls, and side walls that define an interior of the box and a frame support that is positioned within the box and engages end walls and side walls to maintain the end walls and side walls in close conformance at their junction. The frame support also supports an activation frame of an activation kit positioned within an upper opening of the floor box. The floor box is less expensive to manufacture than floor boxes that are manufactured to maintain structural integrity independent of a surrounding concrete floor slab.
