A cable handling apparatus may include a frame and a first cable jaw mounted to the frame. A second cable jaw is pivotally mounted to the first cable jaw so that the first and second cable jaws may be pivoted with respect to one another between an opened position and a closed position. A lock assembly operatively associated with the first and second cable jaws locks said first and second cable jaws in the closed position.
