GCM-02 Coarse-Fine Adjustment Post Holders
The GCM-02 Coarse-fine adjustment post holder provides both coarse and fine height adjustments for posts (GCM-0301). By loosening screw C1, the post can rotate through 360° and its height can be coarsly adjusted. After tightening screw C1 the height can be fine adjusted by turning the large thumbscrew. Screw C2 locks the post in place. The holders can be mounted on magnetic bases (GCM-42), magnetic plates (GCM-43), breadboards (GCM-30), post bases (GCM-53) or directly mounted to an optical table.
