[Bigdog]

Should be stamped at least every foot.

  I just got some chain from a friend that did not want it (50 feet for free).
  It had been given to him. My question is how can I tell what grade it is?
  There are no markings on it, it is shiny almost to shiny to be galvanized.
  He seemed to think it was grade 80, but I think that is what he was told. It
  would be great if it was grade 70 or 80 then I could use it to tie down my
  8N to the trailer (tractor reference). It is 5/16" chain. I was under the
  impression the grades 70 and 80 were stamped.

  Thanks
