Commonly referred to as a "fourth hand," the Park Tool BT-2 Cable Stretcher is a great help when installing and adjusting bicycle derailleur and brake cables. With one hand, the BT-2 grabs and holds the cable in place and pulls the cable taut, allowing you to set the perfect amount of tension and secure the pinch bolt. The convenient ratcheting thumb lock holds the cable tension in place. Made from chrome plated heat treated steel, the BT-2 is built for a lifetime of use, with cushion grips for comfort. A must-have for any shop, home, or professional.
