摘要

The profile (57) has a closed cross section and a surface profile in the form of an undercut longitudinal groove (55). An inner cavity (56) is provided along longitudinal direction of the profile (57). A groove slot (58) is defined by two bars (8) facing away from one another, where the bars are arranged in a step-like manner such that a step (9) of a bar (8) is in each case located on a plane (59) with a step of the other bar (8), where provision is made for two spaced-apart steps, the planes are arranged parallel to one another. Independent claims are also included for the following: (1) a profile connector comprising two sides connected to one another (2) a hook support system consisting a retaining rail for fastening wall, ceiling and floor and different support arms.
