TWIST cables are memory-free! They consist of a multi-strand, steel cable coated with red nylon.
Total size of the needle would equal the cable length PLUS the tip length. For example, an 8" cable with a 4" tip would provide you with a 16" circular. (2 tips = 8" plus the 8" cord).
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.
Small cables fit tips US2 (2.75mm) - US8 (5mm).
