*These are manufacturer’s recommendations and often differ from one marine manufacturer to another, for Grade A shackles the Federal Standard Working Load Recommendation is 1/5 of a defined minimum breaking strength. If comparing between different manufacturers refer to the breaking strength as it is a more meaningful point of comparison.

 

Our Galvanized Hi Test Shackles are 20% stronger than Grade A shackles and are perfect for use with G4 Hi Test Chain. Use one size larger than the chain.

*These are manufacturer’s recommendations and often differ from one marine manufacturer to another, for Grade A shackles the Federal Standard Working Load Recommendation is 1/5 of a defined minimum breaking strength. Our Shackles are 20% stronger than Fed Specifications for a Grade A shackle, thus we can use a safety factor 6 when recommending working load. Our shackles are strong enough to use with Hi Test Chain, just pick one size larger than the chain.
