Abstract: A rough-in box used during the construction of buildings having poured concrete flooring, such as multi-story high-rise buildings. The rough-in box may be used to retain an opening in the floor through which plumbing and mechanical components may be installed after concrete has been poured around the device and hardens into a slab. The present invention also relates to a method comprising the steps of assembling the side walls of a box, placing a lid made of a material stronger than that of the side walls and capable of supporting a weight of 2,000 pounds, placing the box over a hole on the floor, and pouring concrete to form a floor around the box. The box will remain in place providing an accessible penetration through the flooring with space for plumbing connections and a flush surface with the floor over which pallet jacks and workers may travel without obstruction.

Abstract: A rough-in box kit (100) for creating a rough-in box (200) to create a penetration in poured concrete flooring during the construction of concrete buildings. The rough-in box kit (100) includes a single unitary piece (1) having a flat section (5) with: a top end; a bottom end opposite to the top end; an inside surface (5a) located between the top end and the bottom end, and configured to form an inside surface of the rough in box (200); and an outside surface (5b) opposite to the inside surface (5a), and configured to form an outside surface of the rough in box (200). The single unitary piece (1) also has a top flange (3) connected to and extending away from the top end of the flat section (5), and perforations, through-holes, or slots (2) that are formed in the flat section (5). The single unitary piece (1) is configured to be bent at locations corresponding to and lining up with the perforations, through-holes, or slots (2) so as to form the rough-in box (200).
