The GearWrench Locking Flex Head Ratchets have a locking lever mechanism that offers multiple-angle access. The mechanism keeps the handle secured in one of nine positions when the head is angled and a load is applied, so the ratchet does not shift in position during use. The low-profile head may be left unlocked for applications where a range of positions is needed. With a longer reach handle, the 84-tooth gear provides a 4.3-degree ratchet arc, and the ratchets exceed ASME torque performance requirements. The ratchets are available in six different sizes or or as part of three different sets.
