The 16' Heavy-Duty Camera Dolly Track from Proaim is a high-quality track system for the Video/Film Camera dolly. It is designed to offer maximum stability to the Camera setup and operator. The high-grade Aluminum construction offers strength, and the hollow-pipe profile makes it lightweight. The Track can easily bear a total weight of 1764 lb. The spacers keep the two sides of the Track correctly spaced throughout the length of the Track. The end stoppers prevent dolly run-off and give security to your setup. It comes in 4 feet sections with a foldable design that allows easy assembly/disassembly, and the Track is extendable in length up to your requirement.
