  • When sizing a stainless steel shackle for your anchor and Grade 30  galvanized chain, pick a shackle one size larger than the chain and  the shackle will be the same strength as the chain.
  • When sizing a stainless steel shackle for your anchor and Grade 40  galvanized chain, only a shackle one size larger will fit and the shackle will be 60 – 70% the strength of the chain, we recommend to using a mantus swivel to match the strength of the shackle connection to that of the Grade 40 chain.
  • When sizing a galvanized steel shackle for your anchor and Grade 30 galvanized chain, pick a shackle the same size as your chain.
