ABSTRACT:
A support arm for a control device and the like, the hollow profiled walls of which enclose an installation conduit for receiving cables or the like. The support arm, having a simple geometry and great rigidity, comprises a plurality of screw channels which project inwardly and extend in a longitudinal direction of the profiled section and are formed in the installation conduit. The profiled section comprises two lateral walls which are positioned parallel to each other at a distance and are connected at their ends by semicircular connecting elements in the shape of an oval. The screw channels divide the installation conduit into chambers which are spatially connected to each other.
