DESCRIPTION

This low friction ring is suitable for up to ø7 mm line. 

A low friction ring is a simpler and lighter alternative to a plain bearing block. They are produced in black anodised aluminium and have a big inner radius for low friction and an outer slot for attachment of a line or rubber cord. Suitable applications are backstay cascades, barber haulers, kicker tackles or any other applications with static load. 

Here is an example of how to rig a 2:1 jib barber hauler, operated from the windward rail - check out the images:

”Barber hauling” the jib means you pull the clew to windward for extra power and speed. Fixing the line in a pad eye abaft the mast makes for a 2:1 purchase and by leading the line to windward,  an efficient and easy accessible trim device is obtained.  A rubber cord fitted from the low friction ring to the shroud prevents an unloaded ring to chafe on the coach side.
