The cables (steel or coated) move on hardened ball-bearing rollers that roll on smooth shoulder bolts, not bolt threads. Thus the bearing will last longer and not jam after repeated use.
WARNING: The product can expose you to chemicals including Di(2-ethylhexyl) Phthalate, which is known to the State of California to cause birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.
