The Rock Solid Tripod Roller gives wheels to most any tripod and offers mobility for the Tether Table Aero System, monitors, tablets, cameras, and other production gear. Its universal foot attachments securely hold most tripods. The extendable leg bases feature easy-to-turn knurled tightening knobs to quickly secure each tripod leg in the roller. Once secured, the tripod is easy to level and adjust. Simply loosen the dolly extensions and spread to the exact desired tripod height. Lock the dolly legs in place and tighten each tripod leg. The legs lock in place when extended for extra security.
