ABSTRACT:
Locking pliers for grasping an object include a body and a sliding jaw member having a first jaw, the sliding jaw member slidably connected to a body wherein the sliding jaw member may be selectively positioned with respect to the body. A rotating jaw member has an integral second jaw and is rotatably connected to the body. A locking handle is also rotatably connected to the body, the locking handle combining with the rotating jaw member to form an over center mechanism. The sliding jaw member is slidably positioned so that the first and second jaws contact the object. Then the rotating jaw member and the locking handle are urged together activating the over center mechanism to firmly grasp the object.
