3/8" Rotating Ratchet. This rotating ratchet saves time on hard-to-reach nuts. Turn the ratchet handle from left to right until the locking phase is reached. The rotating ratchet can be used as a standard ratchet for tightening and loosening. To change the direction of rotation, simply turn the black knurled wheel, just like with traditional ratchets. Features: ergonomic handle, full-hand operation when tightening to prevent accidental direction changes, and a locking button for added safety. This prevents sockets from accidentally falling off or into mechanisms.
