ABSTRACT:
This invention is an adjustable wrench design having only two movable elements that uses contact points fixed to a movable jaw to hold the movable jaw in position. The contact points act on a guide member to bind the movable jaw from movement when the wrench is under load. Simple rotation of the movable jaw, once the load is removed, permits ready movement of the jaw to a new position.
