Low input torque (160-225 ft/lb) can easily be applied by one person using standard 1/2" drive tools. The planetary gear system provides output torque accuracy of +/-5%. The shearable output drive square is replaceable (1,200 to 3,000 ft/lb models) and the square drive will shear at 3-10% overload torque to protect against expensive internal damage. Built in anti-backlash device / torque holding ratchet (1,200 to 3,200 ft/lb models) maintains the multiplier's input torque allowing the use of ratcheting drive tools. Built in angle of turn protractor Displays multiplier's output angle for use on fasteners requiring a specific angle rotation after applied torque. Furnished with a sturdy carrying case which allows for convenient storage and easy transportation
