摘要： The present invention relates to 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.
