Ronstan Halyard Shackle - Captive pin

Ronstan halyard shackles deliver reliable performance for demanding marine applications. Engineered with lever-action design for quick, effortless opening and closing, each shackle features a keyed pin that locks positively in place—eliminating accidental release under load.

Built from Grade 316 stainless steel, these shackles resist corrosion in salt-water environments and maintain strength through years of active use. The captive pin design keeps components together, reducing the risk of loss at sea.

Available in three sizes to suit different halyard configurations:

RF1032 – 4.8mm
RF1033 – 6.4mm
RF1034 – 7.9mm

Trust Ronstan's proven engineering for halyards, sheets, and control lines on cruising yachts and performance racing rigs.
