Wichard Captive Pin D Shackle - Diameter 12mm - 15/32"

The Wichard Captive Pin D Shackle in 12mm diameter is a professional-grade marine-duty rigging component engineered for demanding tactical, law enforcement, and military applications where equipment security and reliability cannot be compromised. This shackle serves as a critical connection point in load-bearing systems, from rappelling systems and anchor setups to equipment attachment on tactical vests and operational gear. The captive pin design eliminates the risk of losing the retaining pin during dynamic operations—a failure mode that standard open-pin shackles cannot prevent.

Manufactured from grade 316L stainless steel, this shackle delivers corrosion resistance and superior strength in harsh environments—salt spray, moisture, and extreme temperature variations pose no threat to structural integrity. The captive pin remains mechanically connected to the shackle body at all times, even when fully opened, and locks securely into precision-cut indentations on the D-shaped bow to prevent accidental rotation or disengagement. The 12mm diameter (15/32 inch) provides an optimal balance of breaking strength and portability, making it suitable for personal load ratings typical in tactical rappel operations, emergency response rigging, and modular equipment attachment systems.

Law enforcement tactical teams, military personnel, search and rescue operators, and professional riggers rely on Wichard marine-grade hardware for its proven track record under high-stress, repetitive-use conditions. The compact 2 x 2 x 6 inch profile and lightweight 0.4 lb construction make it field-practical for integration into harnesses, carabiners, anchor systems, and emergency deployment kits. Installation is straightforward—the shackle accepts standard rope, webbing, or cable terminations through the open D-bow, and the captive pin mechanism requires no tools or secondary retention devices, reducing setup time and eliminating potential points of failure.
