A mounting system (1) for arranging electric devices (2), for example switchgear cabinets, includes at least one preferably horizontal mounting strip (3) to which at least one device (2) can be secured. The mounting strip (3) includes a support rail (6) to which the device (2) can be releasably fastened and located in a first section (41) of the mounting strip. The first section is central in relation to a cross-sectional view through the mounting strip (3), transversely to its longitudinal axis. A third section (43) of the mounting strip located at a distance from the support rail (6) is at a greater vertical distance (44) from the bottom point (39) of the support rail (6) than a second section (42) at its end that is closer to the support rail (6), especially its end adjoining the support rail (6). The second section is located between the first section (41) and the third section (43).
