This is straight dolly track for the Indie Singleman dolly (or other dollys compatible with PVC track). It totals 12 feet of PVC track with connectors and braces. Two kits can be combined to form a longer run, or combined with Curved Dolly Track to form combination shaped runs.
The dolly is sent folded for shipping. To use the track with the Singleman dolly simply unfold the track, you do not have to unscrew anything. An example video can be found here
