The Ronstan RF1853 Wide D Shackle (1/4" Pin) is a strong, high-capacity marine fitting designed for secure rigging connections where additional clearance and load strength are required. With its wider D-shaped profile, it allows easy attachment of multiple lines, webbing, or larger hardware components compared to standard shackles.

Manufactured from marine-grade 316 stainless steel, the RF1853 delivers excellent corrosion resistance and long-term durability in New Zealand’s harsh saltwater conditions. Its coined pin head design provides a secure, low-profile fastening that reduces snagging while maintaining maximum holding strength.
