Re: Chain - eliminating the weak link
3/8th BBB has a working load limit of 2,650#. If you use a shackle to join chain links then it should be stamped with WLL or working load limit. The rule of thumb is to use one standard size larger for the shackle. The anchor shackle is more of a round shape for joining lengths of chain you can use a chain shackle which has more of a "D" shape than the anchor shackle.
