The Ronstan RF1852 Wide D Shackle (3/16" Pin) is a high-strength marine-grade fitting designed for secure and versatile rigging connections. Featuring a wider internal profile than standard D shackles, it provides additional clearance for attaching multiple components, thicker lines, or webbing.

Manufactured from 316 stainless steel, this shackle offers outstanding corrosion resistance and long-term durability in New Zealand’s harsh saltwater environments. Its coined pin head design ensures a secure, low-profile fastening, reducing the risk of snagging or accidental loosening.

Ideal for dinghies, trailer yachts, and keelboats, the RF1852 is widely used for blocks, rigging attachments, control lines, and deck hardware connections, where extra width and flexibility are required.
