Abstract
Abstract An electrical box includes a U-shaped main body and a pair of sidewalls. Each of the sidewalls includes coupling flanges along their transverse edges and along one of their longitudinal edges for overlapping edges of the main body. In some embodiments, the main body has opposite side edges, each side edges having a pair of flanges extending from a midpoint on a rear panel and along the end panels. The flanges on the sidewall are formed to complement the flanges on the main body to overlap with each other in a coupling relation. The main body and sidewalls are formed from a folded blank. The main body is constructed so that a plurality of identical main bodies can be ganged with the flanges of a first main body telescoping with the flanges of a second main body.
