• the cross section of the adjustment profile has one of its four sides arranged to be open for the whole length dimension of the adjustment profile,
• the open side of the cross section comprises two opposite edge profiles shaped substantially symmetrical to form a linear guide such that the edge profile is arranged to orientate inside a boundary surface limited by the cross-sectional profile of the adjustment profile,
• two parallel adjustment profiles are formed into a two-masted guide frame such that the open sides of the adjustment profiles are facing each other,
• between the two opposite and substantially symmetrical edge profiles formed by the linear guide in the adjustment profile is arranged a moving carriage,
• the motion of the carriage is supported by at least two bearing units supported on opposite edge profiles, and
• the at least two bearing units comprise a groove on their side oriented towards the edge profile for receiving the edge profile.
