Manual Torque Multiplier

The Manual Torque Multiplier is a low-energy input/high-torque output tool that can provide up to 7,000 foot-pounds of additional torque (depending on make/model) for the loosening or tightening nuts, bolts, and other fastening applications. Many models include an anti-backlash feature (i.e., maintains input torque allowing use of ratcheting torque wrenches).

Cost: $210-$1,600, depending on designed input-output ratio
