The Wichard Captive Pin Long D Shackle in 8mm (5/16") diameter is a forged stainless steel rigging component engineered for applications requiring secure load attachment without the risk of pin loss. Built from marine-grade 316L stainless steel, this captive pin shackle combines the structural strength of a traditional D-shackle with a safety mechanism that prevents accidental disconnection—the pin remains permanently tethered to the body even when fully opened, addressing a critical failure mode in high-vibration environments.
The captive pin design features indexed indentations that lock the pin in the closed position, eliminating vibration-induced loosening common to standard shackles. At 8mm diameter, this shackle provides substantial working and breaking loads suitable for tactical recovery, rigging, and load-bearing applications where reliability under stress is non-negotiable. The 316L stainless steel construction resists corrosion from saltwater exposure and harsh environmental conditions, making it equally viable for marine, coastal, and extended-deployment field scenarios where standard carbon steel hardware would degrade.
This shackle is specified for users requiring fail-safe rigging in vehicles, load systems, and tactical equipment where a detached carabiner or pin failure could result in loss of critical gear or injury. Recovery teams, EOD specialists, and maritime operations integrate shackles of this specification into anchor points, tow systems, and load securement rigs. The long D geometry provides clearance for thicker webbing, rope, and attachment hardware compared to standard round shackles, expanding compatibility with field-grade equipment.
Wichard Marine is recognized for producing hardware meeting international maritime standards; 316L stainless steel shackles of this profile are widely adopted in defense and commercial rigging applications where corrosion resistance and load integrity are verified requirements rather than optional features.
