Common Concerns Answered
Is the allen key included with the shackle?
The allen key is not included with the shackle; it is a standard tool that boaters typically have in their marine toolkit for maintenance and rigging adjustments. Its separate nature allows for precise tightening and securing of the pin.
What is the difference between the Working Load (WL) and Working Load Limit (WLL)?
The Working Load (WL) of 2110 lb (960 kg) represents the maximum load the shackle is designed to carry safely in nautical applications, while the Working Load Limit (WLL) of 1190 lb (540 kg) is a more conservative rating specified for industrial applications. For marine use, always refer to the higher WL rating for accurate load capacity assessment.
Why is the price higher than some other shackles?
The Wichard Self-Locking Allen Head Pin D Shackle's premium price reflects its advanced self-locking mechanism, superior 316L stainless steel construction for enhanced durability and corrosion resistance, and its snag-free design. These features provide significantly greater security and longevity compared to standard screw pin shackles, offering a better long-term value in demanding marine environments.
