Hands free operation of a hydraulic torque improves the safety of the operator significantly.

Back-Up Spanners from Enerpac are a hands free tool that eliminates the need to use a flogging spanner as a backing tool. The Back-Up Spanners have been specifically designed to prevent them from locking onto the nut during bolt torqueing operations. They fit easily onto the back nut and prevent it from turning during make up or break out of bolted joints.
