TWIST cables are memory-free! They consist of a multi-strand, steel cable coated with red nylon. This 14 inch/35cm length will make a 24 inch/60cm circular when 5 inch/13cm 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. Available in Small [S], Large [L] and MINI diameters.
