ReactionArm®
Cumulative trauma injuries cost the U.S. billions each year. The ReactionArm reduces injuries to workers' wrists, arms and upper bodies by absorbing the shock of the attached power tool. A power tool mounted on a ReactionArm can easily be moved and positioned throughout the work cell. A variety of styles, capacities and mounting options provide versatility. *ReactionArm shown with optional pedestal, portable base, vertical axes brakes and tool holder. |
