Product Overview
The SS304 JIS Type D Shackle is a professional-grade load-bearing connector engineered for sailors, riggers, caravan owners and industrial users who refuse to compromise on safety or appearance.
CNC-machined from solid 304 stainless steel bar stock, each shackle delivers >25 % higher breaking load than standard commercial shackles while remaining mirror-polished and passivated for lifetime corrosion resistance.
From 4 mm dinghy tie-downs to 38 mm offshore tow bridle, this one product line covers 0.2 t – 8.5 t WLL with a clean, stamp-free deck aesthetic.
