Get the force of a standard torque multiplier without the bulk. These multipliers are less than 2" high, so they fit where you have limited clearance above a fastener. Use them to apply more torque than your wrench can deliver on its own. Internal gears multiply the amount of force (or torque) that can be applied to the fastener. To avoid exceeding the maximum input torque, pair these multipliers with a torque wrench. You can also attach a bracing arm (sold separately) to absorb the backlash after the fastener is tight. Accuracy is rated on the torque output.

To determine torque output, use the torque multiplication factor. For example, if the torque multiplication factor is 3.9X and you apply 100 ft.-lbs. of torque, the torque output would be 390 ft.-lbs.
