I have a large 6 tier Seville Classics shelving unit that I use in my pantry. For years I used it as two 3-tier devices, but because of this block and being stuck at home, I decided to use my time productively by reorganizing my home like a million other people believe. Anyway I decided to make a rack out of this rack and move it to the back wall and as usual I couldn't find my connectors. So I ordered these hoping it would work and to my surprise it actually worked =) I wish they weren't so overpriced but otherwise no complaints.
