Does your Costco carport look like this?

my little mod should make the rings more sturdy, two weld points, as well as provide a nice direct line of force from hammer to ground through the rebar spike, without risk of damaging the ring. Hope this is of value. I'll probably use JBWeld too, since I don't have access to a welder anymore.
