I just purchased 200' of 5/16 G4 chain from West Marine. I bought a Wichard shackle to connect it to the anchor (pic below). The back of the pack says "Functional Limit 1520 KG/3344 LBS" and "Rupture Load 4300 KG/9460 LBS". The chain is rated at 3900 lbs Working Load Limit and 11,600 lbs breaking strength. So all is good until I get home and look more closely at the shackle. It is stamped in the metal WLL 860 KG which is only 1892 lbs.
Soooo I start looking for a shackle that will fit 5/16 chain with a working load close to that of the chain. So far no go. Now I feel like I wasted my money buying G4. What good is it to have a strong chain if the shackle isn't just as strong? Anybody know where I can get a stronger shackle? I called West Marine and the guy looked at every shackle in their catalog and nothing comes close. Even the Acco Anchor Swivel that they say is for use with High Test chain is only rated at 1500 lbs.
