40 Pieces Plastic Storage Cube Connectors Wire Cube Connectors for Modular Closet Storage Organizer and Wire Grid Cube Storage Shelving(Black)

Perfect! These fit perfectly for my c & c cage. The best way to know if these are the same size of your existing connectors is the space in between is too loose with 2 pennies but you can not get 3 pennj s to fit. Someone who these did not work for them left that detail and I tested with my existing connectors. Sure enough these are exact. 2 pennies too loose but too tight to fit 3 pennies.

Product just as described, replaced all missing connections.

Too small for the grids I have. No real way to know that before purchasing.

Needed extra connectors and these were the only ones that fit/matched the panels i had, they work, little over priced but they fit

They were exactly what we were hoping for. The perfect fit for our pet rabbits cage!

These items supposedly have the same measurements as my last batch of connectors for my wire shelves, but they are so tight that the shelves keep popping out and you can't get them on all the way. There is no way they are the same size. If you try to force the wire shelving in, the plastic just breaks. I do not recommend these at all.

They worked perfectly matched the others thanks

I bought these to assemble some extra panels I had that were made with the older, thicker wire. I measured them. They were "three pennies" thick, but also measured 4mm and that is what these connectors were supposed to be. Well, these connectors are loose with 2 pennies, but WILL NOT take 3 pennies. The slots are about 3.9mm and when I measured even more carefully, my wires were more like 4.1 or 4.2 mm and these connectors are very stiff and will not give that much. I got a couple onto my wire grids using the slots around the circle using a rubber mallet. On the 3rd one, the slot broke when I did that even though I could use a rubber mallet with the original connectors with no problems. The slots sticking out on the back were hopeless. I could get a corner part way in and then it would pop right back out. I had three of the original connectors. Their slots were wider and the slots on the back were square, not a truncated triangle like these, and so the old ones stayed on where these would not. I sent these back. I only saw one brand of white ones with the square back slots like mine (my others are black) sold only 4 at a time for over $1.60 each and wound up putting my unit together with just zip ties. It won't hold a full 10 kg/shelf that way, but at least it is stable and didn't cost more for replacement connectors than a whole new unit would cost.
