Ronstan RF9004-09 Dyneema Loop 4mm x 90mm Soft Link

The Ronstan RF9004-09 Dyneema® Loop 4mm x 90mm is a premium soft attachment loop engineered for lightweight, high-load sailing and marine rigging applications in demanding New Zealand conditions. Manufactured from UV-stabilised SK75 Dyneema® fibre, this loop delivers an exceptional strength-to-weight ratio while providing a flexible, corrosion-free alternative to conventional stainless steel shackles and fittings. Ronstan's soft attachment products are specifically designed for modern high-performance sailing systems where reducing weight and increasing efficiency are critical. With a 4mm diameter and 90mm internal length, the RF9004-09 is ideal for attaching Ronstan Orbit Blocks™, low-friction rings, strops, control systems, and other performance sailing hardware. The soft loop design eliminates metal-to-metal contact, helping reduce noise, wear, and unnecessary rigging weight while maintaining exceptional load capacity. Constructed using impregnated multi-strand Dyneema® fibres, the loop offers excellent resistance to UV degradation, abrasion, fatigue, and harsh saltwater environments. Dyneema® is widely recognised throughout the marine industry for providing extremely high tensile strength while being significantly lighter than steel, making it the preferred choice for modern racing yachts, foiling boats, sports boats, and offshore performance vessels. Whether upgrading a racing dinghy, optimising a foiling yacht, or building lightweight control systems, the Ronstan RF9004-09 provides dependable performance and long service life.
