Here is my non-elegant way I've been securing the cages. As I mentioned above, I've had the EB's fall over, but never had the cage come out.
Materials needed; Pliers.
The wire comes from HomeDepot for T-Posts Clips. One side I can leave as is, the other I bend with the pliers.

Ove the years, I also tried other methods: Bungee Cords which worked but too expensive and by the time the season was over, they were garbage as they couldn't withstand the FL sun.
Also tried tying them with cord. Way more time consuming. The better cord is expensive too.
