Wichard Captive Pin D Shackle - Diameter 6mm - 1/4"

The Wichard Captive Pin D Shackle in 6mm diameter is purpose-built for marine rigging, deck hardware, and safety-critical mooring applications where reliability cannot be compromised. Whether you're running a cruising sailboat, commercial fishing vessel, or securing anchor lines and sails, this shackle provides the dependable connection that experienced mariners trust. The captive pin design eliminates the risk of losing a loose pin overboard—a critical safety feature when working on deck in heavy weather or while underway.

Forged from marine-grade 316L stainless steel, the Wichard Captive Pin D Shackle resists corrosion in saltwater environments and maintains its structural integrity through years of exposure. The pin remains tethered to the body at all times—even when fully opened—and locks securely into precision-machined indentations, preventing accidental release under load or vibration. The D-shaped design maximizes working load capacity while reducing snag points, and the 6mm (1/4") diameter suits light to moderate rigging, boom vang systems, shroud connections, and general deck hardware applications.

This shackle is ideal for cruising sailors, fishing crews, and maritime professionals who demand fail-safe hardware in saltwater service. Installation is straightforward—thread or attach the shackle body to your existing rigging eye or fixture, then open and lock the captive pin to join it to your line, sail hanks, or hardware. The compact 6mm size integrates seamlessly into existing rigging systems while the stainless construction ensures decades of service with minimal maintenance. For anyone serious about deck safety and long-term corrosion resistance, the Wichard captive pin shackle delivers engineering reliability at sea.
