Abstract

A frame piece for a rack of a switching cabinet, which has a profile outside and a profile inside, the transitions of which lie at a distance from an outside corner edge of the rack and form a free space with the profile outside to the outside corner edge, for swinging a cabinet door and introducing edges of abutting paneling elements. A frame piece with many possibilities of variation with respect to fastening planes, fastening directions and stability is created according to this invention, because the frame piece is designed as having mirror image symmetry in cross-section with respect to an axis of symmetry which is at an angle of inclination to the rack diagonal. On both sides of the rack diagonal with the profile inside and profile outside, there are at least two profile sections that are at an angle with respect to one another, at least a part of which has fastening seats.
