Common Concerns Answered
Why is this shackle more expensive than standard stainless steel options?
The Wichard HR D Shackle utilizes advanced HR 17.4 PH stainless steel, providing up to a 60% increase in strength and durability compared to standard 316L stainless steel. This premium material and superior engineering justify the higher investment for critical applications where failure is not an option.
What is the difference between the Working Load (WL) and Working Load Limit (WLL)?
The Working Load (WL) of 11,280 lb (5120 kg) represents the safe load the shackle can handle in general marine use. The Working Load Limit (WLL) of 5,290 lb (2400 kg) is specifically designated for industrial applications and should not be confused with the nautical working load for safety-critical rigging.
Can this shackle be used for mooring my boat?
No, this Wichard HR D Shackle is explicitly not for mooring applications. Its design and ratings are optimized for dynamic load applications in rigging and attachment, not for static, prolonged mooring stresses.
