The 9Kg kit contains four metres of screw-together alloy track in one metre lengths. When screwed together the joints are seamless. There are four metres of padded underlay, a T-frame dolly, a low boy (Hi-Hat), and end stops. A cord and ratchet set holds your tripod safely to the dolly. We also include a track cleaning cloth. The complete kit travels safely in its own soft padded bag.
