Ronstan Low Friction Ring - 21mm Hole — Product description
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:
