The holding elements consists of mounting brackets, height adjusters, suction cup extensions, level compensators and also a complete configurable family of Flexible Suction Cup Mount, elements tailored for vacuum-based end-of-arm tools and fixtures found in the automotive body-assembly and final assembly. The parts are designed to fit together for different sizes and applications. The parts are easily mounted on several standard extruded profile systems, not just suitable for one brand of profile. All parts of the same size-category fit perfectly together and thereby create an easy-to-use, compact and flexible/adjustable mounting “assembly kit” for cups.
