Tylaska TR20 Low Friction Rigging Ring Clutch & Jammer Parts Ronstan Series 55 Track ballProduct Description Tylaska TR20 Low Friction Rigging Ring Low friction rigging rings have become a popular alternative for replacing traditional pulleys. Instead of rolling on a pulley sheave, the active line passes through the center hole in the ring and merely slides on the inside smooth radius of this toroid shaped geometry. Another line is spliced tightly around the outside groove of the ring and then spiced back onto itself to create a loop.
