Scott has always been committed to innovation. The introduction of the Works System once again demonstrates that commitment. The Works System is a complete vision system using the same lens for either the Works Tear-Offs or the Works Roll-Off Film System. By utilizing an identical mounting system, the Works System lens allows for hassle-and-tool-free conversion from the Works Roll-Off Film System to the Works Tear-offs System and back. Replacement Canister Motor for the Scott Works System. Side with pull string. Sold individually, Works System sold separately.
