The camera operator seat for the Round-d-Round Doorway Dolly will mount in six different fixed locations.  Steering from both ends of the dolly will allow unlimited camera positioning as the dolly rolls on track with either Hot Buttons or the Matthews Centipede or on the ground with the standard pneumatic rubber tires.  Load capacity is over 1100 pounds (500Kg) and the platform is carpeted for a nonslip, low-maintenance surface.
