Reaction Arm®
Cumulative trauma injuries cost the U.S. economy 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 be easily moved and positioned throughout the work cell. A variety of styles, capacities and mounting options provide versatility. |
Positech's ReactionArm absorbs shock, torsional forces, and impact force from power tools; therefore reducing carpal tunnel injury and cumulative trauma disorders.For Performance and Quality
