The Doorway Dolly from Matthews, also know as the Round-D-Round dolly, represents the next generation in doorway dolly development. Based on the industry standard Matthews Doorway Dolly, the new Round-D-Round model offers all-wheel steering which allows for greater turning flexibility. It's capable of negotiating an extremely tight circle of 1.8 m.

The camera operator is able to mount into six different fixed locations and steering is possible from both ends of the dolly. In addition to being able to mount the seat directly onto the post, the included offset arm can be installed to give the camera operator more choices for seating positions and camera angles. A second seat and offset arm can also be installed, giving you the possibility of having a second person seated on the dolly. This ingenious engineering concept provides virtually unlimited camera and operator positioning as the dolly rolls on track with either Hot Buttons or the Matthews Centipede. Of course, using the dolly directly on the ground with the standard pneumatic rubber tires is another option. Load capacity is over 1100 lb (500 kg) and the platform is carpeted for a non-slip low maintenance surface. This economical yet versatile mobile camera platform is an excellent choice for stage or location.
The Matthews Bazooka adjusts from 61cm to 100cm. Matthews Doorway Dolly provides a particularly stable platform for camera packages up to 45kg.
