Get an entry-level option to add cinematic, linear motion to your films with the MoveOver4 45mm Wide Aluminum Rail 600mm Slider (No Case). It supports up to 8.8 pounds of weight and the carriage glides along a 45mm wide aluminum rail. The rails have two stainless steel rods embedded into it to ensure a smooth and quiet operation. A 3/8-inch 16 screw on the carriage allows you to attach a flat base tripod head for added versatility. The cheese plate on the underside of the rail makes it easy to mount the slider at the center using the multiple threaded ¼-inch -20 and 3/8-inch -16 holes. The bubble level system is integrated into the carriage to provide leveling assistance on uneven terrain.
