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)

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
