Especially beneficial for those with repetitive motion injuries (e.g., carpal tunnel syndrome), wrist or hand disabilities, or limited range of motion, the RoboHandle Ergonomic Tool Adapter is designed to attach to most long-handled tools to help absorb the torque, thus reducing the potential for injury to arm, wrist, or hand. Made of polypropylene plastic and weighing just over 6 ounces, it is designed to cause one to use the stronger upper-arm muscles to maneuver the tool head instead of relying on the weaker forearm and wrist muscles. The RoboHandle comes in two sizes-one to fit handles measuring 3/4 to 1 inch, the other for handles measuring 1 to 11/4 inches.
