Having been around production rigging for most of my career (not a rigger, but I have flown my share of audio arrays). On chain motors, shackle pins always go through the chain to let the dynamic load hanging below to find its center. TBH, there is a lot of contributions to this thread that really don't matter very much (not to belittle yall's contributions at all). Well before a shackle failure or chain failure, the anchor would break out of the bottom (IMHO). Good shackles are extremely strong. That's why they have been around so long and are so widely used. We bought one that was rated the same as our chain (4500#). Does it matter what way they are installed? Probably not. However, I am following what every rigger I have ever met has done... Pin thru the chain.
