The Ronstan RF9005-10 Dyneema® Loop 5mm x 100mm is a premium heavy-duty soft attachment loop engineered for high-load sailing and performance rigging applications in demanding New Zealand marine conditions. Manufactured from UV-stabilised, multi-strand impregnated SK75 Dyneema® fibre, this lightweight soft link provides an exceptionally strong alternative to traditional stainless steel shackles while dramatically reducing rigging weight.

Designed specifically for modern racing yachts, sports boats, foiling craft, and high-performance sail control systems, the RF9005-10 offers outstanding strength, flexibility, and corrosion resistance. The soft attachment design eliminates metal-to-metal contact, reducing noise, wear, and unnecessary weight while allowing smoother articulation under load.

With a 5mm diameter and 100mm internal length, the RF9005-10 is designed to suit Ronstan Series 55 Double & Triple Orbit Blocks™ and Series 70 Single Orbit Blocks™, making it an ideal solution for lightweight, high-load control systems.

Dyneema® is widely recognised throughout the marine industry for delivering extremely high tensile strength with minimal stretch while remaining significantly lighter than steel. Ronstan's impregnated fibre construction further enhances UV and abrasion resistance for extended service life in harsh offshore environments.

Whether upgrading modern sail controls or replacing traditional shackles with a lightweight alternative, the Ronstan RF9005-10 delivers exceptional reliability and performance.
