We recently released our new CAME-TV Camera Slider with no track tubing, which will help save on shipping costs. The track size to use with this slider can be between 30-50mm (1.18"-1.96") OD. When purchasing the track locally, you can determine the length that will fit you requirements and also save on shipping costs. The dolly wheels provide a quiet and smooth movement and the included clamps will secure the track to the end clamps along with clamping on to the spud end of a stand.
