With a 90-tooth gear that produces a working swing arc of just 4 degrees. the Tekton 3/8 Inch Drive x 12 Inch Flex Head Quick-Release Ratchet doesn't need much room to operate. Its 180-degree Flex Head snaps to nine detent positions to work around obstructions. Smaller than low profile. the head is reduced in size in every dimension—height. width. and length. Its polished exterior has a chrome plated finish that's corrosion-resistant and easy to wipe clean.
