Abstract
A locking pliers includes a body that supports a fixed jaw and a movable jaw. A lever is pivotably connected to the movable jaw, and a locking mechanism including a stub arm is coupled between the body and the lever to lock the jaws in a closed position. This locking mechanism includes an adjustment screw that is exposed at an end of the body remote from the fixed jaw. The body forms a resilient gripping surface that extends away from the exposed portion of the adjustment screw. This gripping surface extends beyond the end of the lever by at least about 4 inches such that the lever does not obstruct access to the grip. The user can place both hands on the grip to apply large torques to a clamped workpiece once the locking pliers has been locked in place on the workpiece.
