Wicahrd Self-Locking Long D Shackle - Diameter 5mm - 3/16"

The Wichard Self-Locking Long D Shackle in 5mm diameter (3/16 inch) is a forged stainless steel rigging component engineered to prevent accidental release under vibration and dynamic loading. Built from grade 316L stainless steel, this marine-grade self-locking shackle uses an innovative pin-retention system where the pin locks into precision indentations, eliminating the risk of loosening during operation—a critical advantage in high-vibration environments such as offshore rigging, tactical recovery operations, and demanding load-bearing applications.

The 5mm diameter specification delivers outstanding working and breaking loads suitable for industrial and tactical applications requiring reliable load securement. Grade 316L stainless steel provides superior corrosion resistance compared to standard stainless grades, making it ideal for saltwater environments and long-term outdoor exposure. Each unit is CE marked and batch-numbered for full traceability and compliance verification—essential for professional-grade rigging where certification and load documentation are non-negotiable. The long D-shackle profile accommodates larger diameter slings, cables, and webbing compared to standard shackles, increasing versatility across different rigging systems.

This self-locking shackle serves operators, marine professionals, and tactical teams who require dependable load security in unpredictable conditions. Search and rescue operations, vehicle recovery, offshore deck rigging, and tactical field operations all benefit from the vibration-proof design. Unlike standard shackles that rely on threaded pins prone to backing out under shock loads, this Wichard model's self-locking mechanism provides passive security—no secondary safety devices or constant verification required once installed correctly.
