Chain hanger-gadget

Consider this. The chains on my 10,800# Wildwood measure .333 inch. Thats less than a 3/8" chain. Probably is a Chinese manufacture chain of questionable quality and given FR's push on cost control is probably a grade 30 chain. That means that it might have a strength as low as 1900#. The chains bear no markings (43 or 70). To meet DOT requirements, each chain would have to be a full 3/8" grade 70 chain.

I think the chains the manufacturer installs are mostly cosmetic.
