The Indie-Dolly Curved Track Kit lets you add to your existing dolly track system to increase the range of your camera's dollying movement. With additional kits you can complete a full 360-degree circle with a diameter of 20 feet (6.1m), or you can add to a straight track system to follow your subject from other angles. With its precision-machined dowel pins and black support blocks, the kit provides seamless and smooth transition between tracks and dolly platform, fastening together quickly and securely.
