The GEARWRENCH 120XP Ultra-Narrow Swing Arc Ratchets feature 120 positions for every full rotation, allowing them to turn fasteners with a swing arc of as little as three degrees. All 120XP ratchets have a 60-tooth gear that alternately engages the double-stacked pawls to produce the 120 positions and three-degree swing arc. The double-stacked pawls exceed ASME torque performance specifications. The new extra-long handle models have a teardrop-shaped low profile head and flush mounted on/off switch with highly visible on/off markings designed for improved access in tight spaces.
