An apparatus for fastening and wiring of a plurality of electrical units, particularly in a switchgear cabinet. At least one mounting crosspiece (12-15) accommodating the electrical units on its mounting side can be fastened to at least two bearing rails (10, 11) arranged vertically and behind them, fasteners for fastening the electrical units on the mounting crosspiece (12-15) being provided. This mounting crosspiece (12-15) shaped like a flat strip has, on its rear side opposite the mounting side (29), an integrally formed holding rib (28) extending over its length and having a mounting groove (30) open toward the mounting side (30) designed for accommodating the heads (33) of mounting screws (34) for fastening the mounting crosspiece (12-15) by means of the holding rib (28) on the bearing rails (10, 11). At least one of the two opposite longitudinal edges of the mounting crosspiece (12-15) shaped like a flat strip can be provided with a wiring comb (39). This makes it possible to achieve a very small constructional depth and reduce the number of mounting parts at the same time, the space behind the mounting crosspiece being almost completely usable as wiring space.
