Abstract: A strand grab includes a frame including a mounting portion and a hook portion having a first end attached to the mounting portion and extending in an arc shape to a second end, a gate member rotatably attached to the mounting portion, a jaw member rotatably attached to the mounting portion, and a connector member coupled between the gate member and the jaw member. The gate member, the jaw member, and the connector member are operatively coupled such that when the gate member rotates toward the first end of the hook portion, the connector member causes the jaw member to rotate toward the first end of the hook portion.
