Common Concerns Answered
What is the working load limit (WLL) for the Wichard Self-Locking Long D Shackle 6mm?
The specified Working Load Limit (WLL) for this shackle is 700 lb, but it is designated for industrial applications only. Users should carefully consider this distinction and potentially perform their own load calculations for specific marine safety requirements.
How does the self-locking pin mechanism compare to standard shackles?
The self-locking pin on this Wichard shackle offers enhanced security against vibration-induced loosening, a benefit not found in standard pin shackles. However, some users may find its operation slightly stiffer than conventional designs.
Is this shackle suitable for all marine applications given its WLL specification?
While its robust 3520 lb breaking load and 316L stainless steel construction are excellent, the 'industrial only' WLL designation requires users to exercise due diligence. It is highly suitable for critical rigging where its secure locking is paramount, provided load calculations are appropriately addressed for marine use.
