The Scrim Jim Cine Clamp from Westcott has a long 5/8" post that connects to a stand-mounted grip head to support the frame. For large frames and full tilting, it's recommended that a clamp and stand be used on each side of the frame. The clamp can support up to 22 lb and has rubber grip pads to eliminate slipping. It has a black, non-reflective, protective coating.
