Description:

Ratchet action of a spring-tensioned pawl in the compression handle closes the adjustable jaw. When the compression handle is fully open, the movable jaw is free to slide within the limits imposed by a catch between the main bar and shank of the movable jaw. A link ring in the end of the compression handle can be swung over the end of the main shank to hold the wrench closed.
