I have these wire shelves that are held together with these plastic caps. I'm reconfiguring the layout and ran out of caps. It's been a decade+/- since we got these, and I can't remember the name. Does anyone know where I can get more of these caps? Or, at least, what these caps and/or shelves are called, so I can go hunting for them?
Wow that's a blast from the past. I've still got one that's blue from when i was a kid. Sits in my attic torn down as they always fall apart if u bumped into it wrong.
Searching "wire shelf plastic connectors" on ebay will give you exactly what you want.
Pro tip, if the joints on them are starting to not hold together of their own accord and you don't want them to fall apart: use zip ties on the edges/corners to reinforce them.
