From B&H: "The CineSlider from Kessler Crane is a belt-driven, heavy-duty camera slider supporting up to 80 lb, and this model measures a total length of 60.5" " It is not recommended for use with a single center mount. It is designed with adjustable drag control, which allows you to add resistance to the movement of the slider carriage, allowing for more consistency on slower slides. The drag control knob also works as a friction brake when fully locked down. It does not come with a crank handle, but you can add an optional Kessler Crank Handle at any time. The CineSlider is capable of being motorized with one of several optional Kessler Crane motorized systems, such as the elektraDRIVE, CineDrive, or Second Shooter motion control systems. It can also be enhanced with the optional Kessler Parallax, which will add a panning axis, allowing for inward and outward panning shots."
