This B&H Kit combines a 62" long track with the matching carriage and end caps into a complete Syrp Magic Carpet Slider. The advantage of this slider is it allows you to switch out the track for other-sized ones, sold separately. The system supports up to 15.4 lb and features a brake, bubble level, and reversible 3/8"-16 and 1/4"-20 screw for attaching a camera, ball head, or tripod head.
