This 8″ (20 cm) length can be used with our 4″ (10 cm) tips to make a 16″ (40 cm) circular or connected to other cables. Lifeline holes can be found at each end of these cables. Insert the T-shaped tightening key into the lifeline hole to assist with securing your tip/cable connection. SPIN tips will work with TWIST cables.
