摘要

The system has four parallel profiles and a universal coupling piece in two straight contiguous profiles with front and back sides. The surface of the profile is attached to the piece having a geometry that matches adjustment friction at the ends of the profile. A fixation unit is provided for the profiles, which has an internal hole in the direction of each of the respective profiles.
