The amazing seamless FLEXTRAK can be configured in straight runs that can suddenly 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 20 Kg. 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.
