A switchgear cabinet including rectangular framework of frame members, wherein, in the region of the outside edge corners, free spaces are formed to accommodate angled edges of the double-wall covering members, which abut each other. If at least the angled edges of the exterior walls of the vertical covering member have two angled portions, the interior walls of the covering members with their inner surfaces in the outer planes, directly or via sealing members, fit onto abutment profile sides of the frame members of the framework and are connected in front of the angled end portions of the exterior walls. The angled end portions of the exterior walls extend parallel to the angle bisector of the frame members, which cut against each other, and with their outer corners are at a predetermined spacing from the angle bisector, and thus security against vandalism is improved in the region of the outer edge corners, without impairing the symmetrical appearance of the outer edge regions and the arbitrary attachment of the double-wall covering members and cabinets doors on the framework.
