TWIST™ cables are memory-free! They consist of a multi-strand, steel cable coated with red nylon.  This 37″ (93 cm) length will make a 47″ (120 cm) circular when 5″ (13 cm) tips are attached. 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. Available in Small [S] and Large [L].
