Extended reaction tubes fit into restricted spaces that prevent the use of standard reaction arms. They replace the arm on a compatible low-profile hydraulic torque wrench. These tubes absorb the force exerted by a hydraulic torque wrench when turning is complete to prevent torque from transferring to the operator and causing injuries or fatigue. They position the wrench against a reaction point that stops the wrench from rotating backward and twisting the operator's hand along with it.

Backup spanners hold one end of a fastener in place while the other end is turned by a hydraulic torque wrench. They allow the wrench to tighten or fasten nuts and bolts rather than just spinning them. These spanners grip tightly without seizing onto the fastener, so they can easily be moved from one fastener to the next.
