Selden Low Friction Rings
LOW FRICTION RINGS
A low friction ring is a simpler and lighter alternative to a plain bearing block.
- Produced in black anodised aluminium
- Big inner radius for low friction
- 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.
BARBER HAULING WITH LOW FRICTION RINGS - ”Barber hauling” the jib means you pull the clew to windward to increase the pressure on the leech. 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.
