¹ Stock units are calibrated with equal cw and ccw slip torques corresponding to the tabulated Upper Limit Torques. Other torques are readily availabe from full, down to 1/8 of the upper limit torque for each model. Torque values are independent of each other for cw and ccw rotation, and may be specified the same or different for the two directions.
