Common Concerns Answered
Is the pin on this shackle prone to loosening?
No, the Wichard Self-Locking Allen Head Pin Bow Shackle features an innovative self-locking mechanism where the pin engages indentations, actively preventing it from loosening under vibration or load. This offers superior security compared to standard screw pin shackles.
Is the WLL rating confusing for marine use?
The shackle has a Working Load (WL) of 1320 lb (600 kg) and a Breaking Load of 3300 lb (1500 kg), which are directly applicable to marine environments. The separate WLL of 660 lb (300 kg) is specified for industrial applications only and should not be confused with its robust nautical rating.
Why is this shackle more expensive than standard screw pin shackles?
The higher price reflects the advanced engineering of the self-locking pin mechanism and the superior grade 316L stainless steel construction, which together provide significantly enhanced security and durability, minimizing the risk of snagging and accidental release in demanding marine conditions.
