M.U.S.T. is an interlocking modular system, in which the individual components can be universally combined with each other through intelligently solved interfaces. Thanks to these firmly defined interfaces, the system can be expanded at any time as desired. Thus, the user can easily combine M.U.S.T. components that have been procured subsequently or developed in the future with his already existing M.U.S.T. components. M.U.S.T. thus offers the user the right system for every situation he is confronted with.
