The Ronstan RF9004-08 Dyneema® Loop is a premium lightweight soft attachment loop engineered for high-performance sailing, modern rigging systems, and marine applications in demanding New Zealand conditions. Manufactured from UV-stabilised SK75 Dyneema®, this 4mm x 80mm loop provides an exceptionally strong, corrosion-free alternative to traditional stainless steel shackles while significantly reducing overall rigging weight.

Designed specifically for use with Ronstan Orbit Blocks™, low-friction rings, soft attachment systems, and performance sail controls, the RF9004-08 offers outstanding strength-to-weight performance while maintaining excellent flexibility and durability. Dyneema® is widely recognised throughout the marine industry for delivering extremely high tensile strength with minimal stretch and exceptional resistance to UV degradation and fatigue.

The flexible loop construction eliminates metal-to-metal contact, helping reduce noise, corrosion, and unnecessary weight while improving rigging efficiency. Its compact 4mm diameter and 80mm internal length make it ideal for attaching blocks, strops, control systems, and lightweight hardware where performance and reliability are critical.

Whether you're racing an ILCA®, skiff, sports boat, trailer yacht, or offshore yacht, the Ronstan RF9004-08 Dyneema Loop delivers dependable high-load performance with minimal weight.
