The Ronstan RF1033 Halyard Shackle (1/4" Pin) is a robust, mid-range snap shackle designed for fast and secure attachment of halyards, sheets, and control lines. Featuring a spring-loaded snap closure with lever-action release, it allows quick one-handed operation—even under load—making it ideal for both cruising and performance sailing.

Constructed from marine-grade 316 stainless steel, the RF1033 offers excellent corrosion resistance and long-term durability in New Zealand’s demanding saltwater conditions. Its captive pin and closed-eye design ensure the halyard remains securely attached while preventing accidental loss of components during operation.

With a larger pin size than the RF1032 and lighter weight than the RF1034, this model provides a perfect balance of strength, usability, and versatility for a wide range of sailing applications.
