The TUF 1497 tool balancer retractor is designed in such a way that retraction force increases as the cable is extended. As a result, the attached tool is returned to its starting position by the retractor after use, leaving the workbench free for other tools or items of equipment. An assurance of precision work is provided by the shallow rising graph representing the progressive increase in spring force. The use of special plastics for the housing and cable drum, combined with specially selected material for the spring, makes these models the ideal aid at the workbench.
