The Sirui Video Survival Kit 2 Tabletop Dolly with Slider Track or VSK2 is a basic slider kit with a slider dolly that also functions as a tabletop dolly for use on smooth surfaces. The slider dolly is a raised platform with front and rear articulating wheels which allow it to make turns when used on a smooth, flat surface. The front and rear wheel axles are independent of each other, allowing you to adjust your turn radius.
The slider track consists of four 15mm diameter carbon fiber rods, and it comes with two couplers and two end stops. This allows you to assemble a dual-rail track that is 34" long. Mounting the slider dolly on this track provides approximately 17" of travel along the rails. The track provides a smooth platform for the dolly, but it is only meant to be placed on a flat surface and cannot be used on uneven or angled surfaces.
