Review on HAPY SHOP Connectors Organizer Shelving by Michael Cooper

I bought these to mount some extra panels made from old thicker wire. I measured them. They were "three cents" thick, but they were also 4mm, and that's what these connectors were meant to be. Well, these connectors cost 2 kopecks, and 3 kopecks WILL NOT. Slotted around 3.9mm and when I measured even more closely my wires were more like 4.1 or 4.2mm and these plugs are very stiff and don't deliver that much. I skewered a pair onto my wire mesh using the snips around the circle with a rubber mallet. On the third, the slot broke, although I could easily use a rubber mallet with the original connectors. The slits sticking out of the back were hopeless. I could partially insert the corner and then it would pop out again. I had three original connections. Their slits were wider, and the slits on the back were more square than truncated triangles like these, so the old ones stayed where they weren't. I sent these back. I've only seen one brand of whites with square back slots like mine (I have other blacks) that only sold 4 at a time for over $1.60 each and I ended up assembling my unit using just zip ties. So it won't handle a full 10kg per shelf, but at least it's strong and doesn't require the additional expense of replacing connectors as a whole new unit.
