Reelcraft TB Series, spring retractable tool balancers attach to tools through a cable hook to lift them and reduce operator fatigue in assembly lines and workstations that require frequent use of tools. They feature a composite / steel reel housing with a tensioned retractable spring for extending & retracting the 6 / 8 inch cables. These tool balancers are integrated with zinc plated carbon steel cables with a safety latch for tool attachment. They increase productivity by keeping tools positioned over the work areas, to require minimal operator movement and prevent tools from being accidentally dropped. Selected models come with a locking ratchet for locking the cable in place to move the tools around a fixed area. Choose from a wide range of these tool balancers, available in maximum load capacities ranging from 1.5 to 10 lb.
