Description
Ronstan Low Friction Rings deliver an ultra-lightweight, compact solution for line deflection and static load management. Designed through extensive testing and development, these rings achieve an optimal balance of strength, weight, and wear resistance, making them ideal where the minimal moving parts of a block are unnecessary.
Machined from high-grade aluminium and finished with a durable low-friction anodised coating, they provide excellent resistance to corrosion and abrasion while ensuring smooth running for a wide range of lines. The deep, secure lashing groove guarantees reliable performance under load while keeping lines correctly aligned.
These rings are trusted in both Grand Prix racing and everyday cruising setups, offering a simple, maintenance-free alternative to traditional blocks.
