The Story
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
Specifications:
- Color: Black
- Box Dimensions: 1"H x 2"W x 3"L WT: 0.1 lbs
- UPC: 9316800525966
