The GF-3D Combi-rig is a solution for providing a stable mount for large camera packages and 3D Rigs on a centre post dolly. Two 80 mm diameter tubes from the standard GFM Combi-rig can be used in combination with the »double tube« top and bottom mounts. The bottom mount has a Euro-adapter that allows for lateral adjustments and accommodates off-set ball adapters as well as off-set 3 and 4 way levellers.
