Torque Reaction Arm Selection Information
Torque reaction arms help absorb reaction force that would otherwise be transferred to the operator during fastening. They can also help maintain controlled tool positioning and improve ergonomics in repetitive assembly applications.
Confirm the tool weight, maximum reaction torque, required working reach, tool diameter and mounting location before selecting an arm. Kilews West offers auxiliary, economy and telescopic configurations for different assembly layouts and driver sizes.
Auxiliary torque arms provide flexible support for compatible Kilews West drivers. Telescopic KP-AUX-B50 models provide extended working range with wall mounting, while the KW-TRA1 economy torque arm provides an adjustable-height parallel-arm solution for compatible lower-capacity applications.
