Norbar torque wrenches offer unparalleled quality,
accuracy and durability.
 

Electrode Wrenches

The correct tightening of carbon/graphite electrodes is known to increase the energy efficiency of electric arc furnaces and prevents electrode sections from being lost in the furnace.

Norbar Electrode Wrenches are based on two well proven torque wrench designs: electrodes up to 8 inches use the 'Professional' type, 9 inches and upwards are based on the 'Industrial' wrench.

  • Positive torque control increases energy efficiency.
  • Self-clamping action speeds the tightening operation.
  • Unmistakable signal when the set torque is reached.
  • A wide range of electrode sizes, 3 to 24 inches, can be tightened.
