The 47.3" long Konova K2 Slider supports loads up to 39.6 lb and features roller bearings that provide smooth, stable, and quiet operation. The slider can be supported using a single tripod or a pair of tripods/stands thanks to 1/4"-20 threads located on the underside of the track and positioned at the center and at either end. Additionally, there are threaded holes at the sides of the slider that enable you to mount it vertically, for expanded creative possibilities. For ground-level shooting, a pair of height and angle-adjustable legs with rubber ball feet that screw into the sides of the slider are included.
