Abstract

A frame piece for a rack of a switching cabinet. With minimum material an optimum result is obtained with regard to fastening planes and fastening direction as well as stability. A profile inside and a profile outside are used to form the frame piece as a closed hollow profile with one or two longitudinally directed hollow spaces. The profile outside delineates a free space to an outside corner edge of the rack. The profile inside has a profile section with several rows of fastening seats or several profile sections at an angle with respect to one another with at least one series of fastening seats. The profile inside and the profile outside form outside edges in a region of the right-angled abutting outsides of the rack. The outside edges are designed as double-layer sealing struts or connected to them in a direction to the outside corner edge connecting struts with or without receiving grooves for sealing elements.
