Abstract

A framework made of frame pieces for a switchgear cabinet, wherein the frame pieces are preferably laterally reversed in relation to their cross-sectional diagonal and have profiled sides perpendicular to the outer sides of the framework and have fastening recesses. In an area of an inner side, the profiled sides end in sections that form a recess for fastening mounting rails. By combining several known and novel features, a framework having easily manufactured frame pieces is created which optimally meets all requirements for use with a switchgear cabinet.
