Ronstan RF9003-07 Dyneema Loop Link 3mm x 70mm

The Ronstan RF9003-07 Dyneema® Loop Link is an ultra-lightweight, high-strength soft attachment loop designed for modern sailing, high-performance rigging, and lightweight marine systems in demanding New Zealand conditions. Manufactured from premium UV-stabilised SK75 Dyneema® fibre, the RF9003-07 delivers exceptional strength-to-weight performance while providing a flexible low-profile alternative to traditional stainless steel shackles. Engineered specifically for Ronstan Orbit Blocks™, the RF9003-07 suits Series 30 Double & Triple Orbit Blocks™ and Series 40 Single Orbit Blocks™, allowing direct soft attachment without intermediate metal hardware. The lightweight flexible design helps reduce rigging weight, minimise rattling hardware, and improve sail control responsiveness in dinghy racing, foiling, skiff, and sports boat applications. Ronstan manufactures the RF9003-07 using impregnated multi-strand SK75 Dyneema® fibres for improved UV resistance and abrasion durability in harsh marine environments. Dyneema® is widely recognised within the marine industry for offering extremely high tensile strength while remaining significantly lighter than steel. Ronstan states the RF9003-07 is “10 times stronger and lighter than steel.” With a 3mm diameter and 70mm internal length, this Dyneema® loop is ideal for lightweight high-load sailing systems, soft shackling, low-friction ring attachments, cascading vang systems, and performance sail control applications where reduced hardware weight and flexibility are essential.
