i need to know where i can get replacement chains for the API treestands

I would contact Bass Pro Shops (Redhead) and ask them that question. They, reportedly, were the ones that took the API line over when they went bankrupt at the beginning of last year.

You may still try their original website. I forget the url but typing in API treestands in your search engine should get it relatively quickly. Last summer they were still supplying parts to dealers.

Check ebay.

I called API themselves back in October when a bear ate the foam padding on the arm and foot rest.

Bowhuntercop,
You weren't in it hope!!
