They're literally their carports - they even have a sign on them telling you how to order one for yourself.
I think they don't have dividers because they also take the large lumber carts, too.
Home Depot also has no dividers, probably for the same reason.
I had to check the Menards website. I knew Menards sold everything but it never dawned on me that they literally sell those carports. I didn't know that's what those structures were called either. That's a good point about the large lumber carts.
Apparently they sell 613 variations (mostly different lengths and heights and widths, probably four parts total).

Of course, Menards sells entire houses (in kit form): https://www.menards.com/main/building-materials/the-project-...
And milk. https://www.menards.com/main/grocery-home/grocery/dairy-eggs...
That's pretty amazing. I didn't think any retailer sold house kits akin to the Sears catalog homes I've read about.
Not a bad price.
