I'm not employed by nor do I recieve any compensation from Ace Hardware but I will say that if you check with them you'll find they carry #41 chain, half and master links. 41 is a good alternative to 415 or the kit supplied chain.
Most industrial suppliers, Grainger, Tractor Supply, and others as well as ACE carries #41 chain. I think you'll find it will work well for you.
