Konova Tripod Stability Arms for Slider (2 Arms In) This product allows increased stabilty when using a slider on a single tripod and eliminating(canceling) the need for a second tripod. The extending arm allows you to set the slider at a level horizontal position or at an angled, the tilt postion. Actually one arm provides enough stability, however we recommend using 2 arms for angled tilt slider shots. It attaches to the tripod with the c clamp and fits most tripods. Not only Konova slider, it also fits other branding sliders. Including 2 piece of arms, please know camera, slider, tripod not included
