Park Tool BT-2 Fourth Hand Cable Stretcher with locking ratchet. New, $48.00/each

Part# 16261-P

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.

Nicely made, brilliantly designed

Note the tool is being held open against the spring tension with the thumb lock

Here's the other side of the 4th hand.

Park Tool OBW-3 offset brake wrench with 14mm opening and brake centering tool. New, $10.00/each

Part# 16122

• We have three in stock
• Park Tool says this about the OBW-3: We call these our offset wrenches because of their unique design, which allows them to be used in tight places, such as centering caliper brakes. OBW-3 has a 14mm opening, and the other end fits into the tension springs to rotate the brake on its bolt.

The left side is for centering brakes.
