''Anywhere there's a high torque, confined space situation, a torque multiplier should be close at hand. Not only will a torque multiplier help make sure your fasteners are properly tightened, but it will help improve worker efficiency -two things which add up to an increase in productivity. Through a relatively simple arrangement of gears a torque multiplier makes the toughest nut-turning jobs a snap. The gear train of such a tool increases the mechanical advantage of a ratchet in direct proportion to the gear ratio of the multiplier. For instance, using a GA184A torque multiplier, which has a gear ratio of 4.0:1, and then applying 100 lb. ft. of input, the result will provideapproximately 400 lb. ft. of torque to a threaded fastener.''
