Ronstan Low Friction Ring

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
