Used to multiply applied force for setting and removing high torque fastenersPlanetary gear system multiplies input force many timesTorque multipliers lower physical effort, resulting in smooth, steady application of torque and increased accuracyPermits application of high torque without use of a long leverCan be driven with a torque wrenchKit includes straight and 90° reaction bars with reaction base (base not included in 719071 kit)90° bar and base rests against truck wheel rims when used to torque lug nutsHigher ratios require lower input forces, reducing operator effortAll models include breakaway input adaptor to protect wrench from overload
