Spools. Yep, that's the same stands I got.
I figure if the boltholes in the height adjustable area of the stand are not exact it will cause an exaggerated tilt. Which it did. My garage is level. I can fix it by wallowing out the boltholes on one side but still, I shouldn't have to. I guess you read their responses, pretty sad. They offered me 15%, and a cookie. I declined.
