Wichard Self-Locking Long D Shackle - Diameter 4mm - 5/32"

The Wichard Self-Locking Long D Shackle in 4mm diameter is a precision-engineered rigging and recovery component trusted by military and tactical professionals who demand reliability under extreme load. This shackle is designed for applications where a secure connection cannot fail—from rappel systems and fast-rope deployments to vehicle recovery, load-bearing harnesses, and emergency egress operations.

The long D-shape geometry provides superior strength distribution and simplifies attachment to carabiners, webbing, and anchor points without sharp edges that could compromise synthetic fibers. Wichard's self-locking mechanism eliminates accidental opening through vibration, impact, or personnel error—a critical safety margin in high-stress tactical environments. The shackle is made from marine-grade stainless steel and weighs 0.1 lbs, making it ideal for load-bearing systems where weight reduction directly impacts operator mobility and mission success.

Law enforcement tactical teams, military units, rescue operations, and professional riggers rely on Wichard shackles for life-safety applications where equipment redundancy and single-component reliability are paramount. The self-locking pin design keeps the shackle closed under tension and shock loads without requiring tools or secondary safety measures, reducing setup time and eliminating failure points associated with manual pin retention or improper securing methods.
