Our Underslung mounting system for Camera Sliders is easy to setup and use, and is fully adaptable to your existing Slider. We sell the Underslung as a modular kit that takes advantage of capacities built into our original slider design, such as the double rails and many of the through-holes present on our carriage. The Underslung can be used with the Hi-Hat and a mount of your choice. The entire system takes less than three minutes to assemble and supports the same load as the Slider. With two Hi-Hats, you can have cameras mounted on the upper carriage and the Underslung mount simultaneously.
