Ronstan Low Friction Ring - 21mm Hole RF8090-21

Low Friction Ring - 21mm Hole

Low Friction rings can be used as a lightweight alternative to a block in some applications. They are best suited for systems requiring relatively small line deflection angles, or for high static loads.
The design achieves a nicely rounded internal profile for smooth control line trim under load, and a deep external groove to retain the rope securely within the large shoulders when spliced into a loop.

Features:

• Compact & lightweight
  
• Low friction
  
• Large shoulder secure allowing for rope lashing
  
• Durable
  
• Simple & reliable design
  
• Low maintenance
