Description: |
| The ratchet has a spring lever that shifts and provides the spring action of a "U" shaped pawl which can be adjusted to allow ratchet action in two directions. The head has a double-sized opening, and anticipates an extended shank with additional sockets, drill chuck, etc. A stud on the handle holds the setting of the spring lever for the pawl. |
