The device has square frames mounted at a distance from each other and with parallel planes on the wall. In the interior of the frames extend ducts, preferably of a lattice structure, which are exchangeably disposed. Furthermore, the frames are used as supports for exterior facing plates. One of the sides of the frames is connected via a hinge with an adjacent side and (together with the facing plate fastened thereon) is outwardly pivotable. Apparatus supports for electric sockets, etc., are mounted in optional locations, also inside the frame cross section, on ducts or on special intermediate supports. Great flexibility with respect to the total cross section, arrangement, fitting with apparatus and choice of facing is made possible.
