I fell back to hanger straps... I was in the garage and the installer used that stuff for my garage door motor and its been up there for over 20 years. I figured it would work on this little transformer holding it down. I wrapped it around the metal core of the transformer, slipped in the original screws (needed to drill the holes a bit to line up with the base), and then pitched it together at the bottom with a new screw/nut keeping it tight.
With the savings of buying random metal parts to make another type of brace I am going to get a new power cord that has a outer cloth covering. I found this place online that has a great selection:
