The E391 Enerpac E-Series Manual Torque Multiplier provides 1,200 ft-lb maximum output torque from a manual torque wrench input. Its planetary gear system multiplies input torque at a 6:1 ratio, making it suitable for controlled high-torque industrial bolting where a powered torque wrench is not required.

Selecting a Manual Torque Multiplier
Select the multiplier based on the required fastener torque, available reaction point, input torque-wrench capacity and required drive size. For the E391, do not exceed 200 ft-lb input torque or 1,200 ft-lb output torque. The reaction bar must bear against a structurally sound reaction point before torque is applied.
