This package is the COMPLETE HD KIT 12ft. which also comes with the Dolly Accessories; Seat, pull-bar and track wheels (Does NOT come with track - I generally use 1 1/2 inch PVC in 10 foot lengths) -- This is the original Kessler Crane! The industry standard in lightweight camera crane systems. Featuring 360 degree rotation, an invertible camera platform for under or over slung camera positions, a two arm design for maximum stability and built with high-grade anodized aluminum the Kessler Crane is as robust as it is functional. Easily broken down for transportation and uses standard household style weights to achieve proper balance.
