Extension Sets are the core of the Stage One system. Each set includes two threaded detachable rails using precisely machined tubes and inserts to ensure excellent seamless alignment, and one mid-span support. Extension sets require a Stage One Hardware Set which includes the cart and end brackets to be fully functional.

Each extension set adds 21 inches of total length to your slider. The mid-span support keeps your cart on the rails and provides an attachment point for standard supports, including tripods with 1/4-20, 3/8-16, or light stand heads.
