The Steelman PRO Cobra Series Locking Flex-Head Ratchets work in three different modes including the Full Flex Mode, which allows the ratchet to flex into seven different positions; the Flex Lock Mode, which locks the ratchet into one of the seven fixed positions; and the Breaker Mode, which allows it to perform just like a standard ratchet. Each Cobra Series Flex Head Ratchet features a 90-tooth gear mechanism requiring only a 2.25-degree swing arc. An ergonomic, dual chrome and TPR grip ensures the hand won’t slip in the toughest of applications. These ratchets come in 1/4”, 3/8” and 1/2” drives in long and extra-long lengths.
