I have a set of the Home Depot 5/16 chain, and I think another set is from Harbor Freight. I bought it because it matched up with the ratcheting load binders I had. I agree that 5/16 is probably overkill for anything my 2520 will try to pull or lift. Heck, you could probably lift two bare 2520s up off the ground with one 5/16 chain.
