A prefabricated junction box and lid for use in the floors, walls and ceilings of a building. The junction box has tubular projections extending from an exterior sidewall and sealed by removable knockouts. When a knockout is removed, angular tabs form a locking ring within the tubular projection so as to retain corrugated electrical conduit inserted therethrough. The junction box lid includes locking tabs aligned with each tubular projection which substantially improve the capacity of the box to retain electrical conduit. |
