The multifunctional Machine Construction System MS 40+ (40 mm spacing system) has been designed on the highest demands on safety, flexibility and modern appearance. It persuades with excellent levels of stability and a harmonic design. The MS 40+ system joints make assembly fast and efficient, in many cases with no machining work necessary either to open profiles. The range of profiles from the MS 40+ system consists of open profiles in types L (Light), B (Basic), H (Heavy) and U (Ultra) for moderate to high static and dynamic demands, and closed profiles in types BC (Basic Closed) and HC (Heavy Closed). The range is complemented by a variety of angular and round-edged profiles. All series come with a standardised outer radius of 1 mm to avoid visible cut edges and dirt traps.
