Load Rated Hot Dip Galvanised Bow Shackles

Load-rated bow shackles are much stronger and more durable than regular galvanised shackles, for four good reasons:

  • Drop Forging Manufacturing Process:
    • Drop forging increases the break load and toughness of the steel by matching the grain line to the contours of the component.
    • Drop forging steel is stronger, more robust, and more dependable than machining, casting or fabricating (welding)
  • High Tensile Grade 6 Carbon Steel - stronger than standard mild steel
  • Narrower Jaw Width - the shorter span increases the flexural strength, reducing the potential deflection (bending)
  • Increased Pin Diameter - Larger cross sectional area improves flexural strength (the ability to withstand a transverse bending force)

Load Rated Bow Shackles are finished with a hot dip galvanising treatment for extra corrosion resistance. 

Load Rated Shackles are appropriate for anchoring, mooring and other load critical applications -  the internal rounded space created by the bow shape allows extra articulation for taking loads at changing angles.

Each shackle is manufactured to US Fed Spec. RR-C-271 and embossed with:

  • CE = mark of approval
  • WLL =  The Working Load Limit
  • Size = The Body Ø (D1)

A certificate is available on request

WLL = Working Load Limit

MBL = Estimated Manufacturer Break Load

The Load Rating Safety Factor applied = 6:1

Therefore the estimated break load = WLL x 6
