After searching for connectors to use some REALLY old metal, lattice and cube shelving, they came close to the black ABS plastic connectors originally supplied. I was happy to buy a large set of 24 for parts due to the possibility of connector/key parts loss due to repeated use in various environments including college. The exact size, shape and function of the round black shelf connectors are of paramount importance in creating additional storage space. The key before ordering was close-up photos provided by the manufacturer. The connectors I received were well packaged and appeared to be 80% closer to the correct size, shape and configuration of the originals when purchased as replacements. I used about half the plugs I received and they all fit almost perfectly. Due to the uneven thickness of the original metal shelves, this seemed to be a big problem every time I tried it on. Basically, patience is key when using connectors as not all shelves fit perfectly or easily. (That can be frustrating if you're not in the mood to make it work!) Some shelves barely fit within an eighth of an inch, but if you manipulate three corners in a connector and apply the same pressure, the connector barely keeps up. It really works! Don't load your shelves with heavy items, but I reckon they can hold up to ten pounds or less. { This is a complete guess that can be verified by someone else who has more time. } *Tell your college students again to be very patient when inserting the shelves into the slots and in the end everything should fit together. As there are some connectors that could work as suitable replacements I'm glad we were able to find one to make our shelves usable and we will definitely be buying it again. Thank you for being available and please keep offering them for people to buy. who has shelves made of metal cubes from 20 years ago! :)
