The new vertical rig adds more functionality to the camBLOCK system, utilizing it's versatile design.  The vertical rig kit includes dual-track-clamps that attach to the existing track spreaders to create a second smaller track on the back of the dolly track.  A wheeled weight assembly is held captive on the rear track, and provides the counterweight to the system through a simple pully/cable method. Because the wheeled weight assembly is held captive by the rear track, the system can be held at any angle.  Two lengths of track (5ft) is pictured, but the height of the vertical rig can be increased up to 21 ft with the addition of more track.
