Low Friction Rings are ideal for applications such as barber haulers, spinnaker twings or other uses that have small turning angles and little line movement. They also work great for backstay adjusters when used in a high purchase cascade configuration. Ferrules start having frictional heating and wear problems when there is significant line movement so conventional pulleys are still better for applications such as mainsheet and halyard blocks.
Tylaska’s Low Friction Rings span an extreme range of working loads and line sizes that no other single manufacturer provides.

Lighter and smaller than a conventional pulley block, low friction rings have become a popular alternative for many applications where traditional blocks once ruled. In addition to being light and less expensive than convectional blocks, low friction rings are also less prone to failure because there are no pulleys to crack or bearings to foul.

Instead of rolling on a pulley sheave, the active line slides on the inside smooth surface of the ring. Another line is spliced around the ring as an anchor.
