This amazing seamless dolly track can be configured in straight runs or can curve in any radius or direction. The basic unit is 40′, which will loop to make one 17′ run. 2 pieces side by side will create a 40′ run. Each section rolls up into a 2′ diameter bundle and weighs 30 lbs. creating unprecedented portability for a track rigid enough to support an operator, yet flexible enough to curve into a 90 degree turn with a 2′ radius. The key to FlexTrak’s success lies in the unique capability of our Spider Dolly’s track wheels, which are designed with an articulating arm on one side to compensate for any deviation in the track spacing. Set-up time is almost instantaneous.
