Highly stable holding of large and heavy workpieces with a well thought out system of solid modular elements, that cannot rotate when joined together. Base plates with a 25 mm grid support components of the module system with which any vertical or horizontal position can be achieved and held even under heavy loading. Where accurate repeat positioning and clamping is a concern, the elements from the SPANNFIX program are the ideal choice. They perfect the QUADERFIX system. The result is an unrestricted basis for measuring fixture solutions through the universal system thinking of dk-Fixiersysteme over and above the actual QUADERFIX program. This product film shows the positioning, operating principle and clamping princilple of QUADERFIX using a few exemplary components.
