I don't know the manufacturer. But, if your goal is to obtain some, you can
buy those relays from Array Solutions:
Scroll to the bottom. You'll see he sells the relays individually for $45
each... same relays used in the RatPak, SixPak, etc.
If you really just want to know who makes them, perhaps if you call or email
Jay he will tell you.
