Product 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. This loop can then be wrapped around the tree in a choker hitch configuration to secure the rigging ring to the tree.  While there is some added friction from the sliding action the frictional loss is generally small.  In many applications this added friction is actually welcome as it helps to somewhat reduce the force required to control the load. Lighter, smaller and less expensive than a conventional pulley block, low friction rigging rings are also less prone to failure since there are no pulleys to crack or bearings to foul.  Their simple design make them practically indestructible. 

Extreme duty TR series rigging rings offer exaggerated width for improved bend radius.  Designed in conjunction with arborists, the TR series rigging rings are designed for extreme duty.

The FR series low friction rings offer increased wall height for complete line security.  The thinner wall width reduces weight which is useful for sailing applications where reducing weigh aloft helps with performance.

WARNING: Inspect low-friction coating, splices, and line condition before each use. Use professional, qualified splicing to tightly secure low friction rings. Keep rigging and hardware clean and free of abrasive particles. Always follow loading, safety factor, and temperature ratings recommended by line manufacturer. Always monitor heat buildup at the low friction surface and its affects on temperature sensitive rigging lines. Elongation of ring occurs beyond the MBS rating. Do not use rings that are deformed or missing low friction coating.
