E-outstanding Metal Rack Connector 4pcs 1Inch/25.4mm Wire Rack Shelve Unit Pole Connector Storage Shelf Shelving Holder Connection Nuts Replacement Parts (ID: 16mm, OD: 23mm)

Fit and work great. Although its doesn't seat completely hidden within the rod like the original part that came with the shelf, it does its job flawlessly. Most definitely worth it.

These fit the Amazon basic black metal shelf I bought from Amazon a while back. The inside opening measured 7/8 inches, when I measured it. Be sure to look closely at the center ”ridge” as it was different from the original. The original was one ridge while the ones I just received are 2 ridges. As I bought a set of four it is ok. Otherwise it would off set the height of the poles and thus also the shelf connectors: the shelf wouldn’t sit straight.

Don't work with (mine) one inch poles

I can confirm that these worked with my 48” and 36” wide Alera shelves.

These actually fit the 1” poles for an HDX wire shelving unit. The first order for Howdia brand were too small and did not fit. Thank you!

I lost some of the hard ware to my bakers rack during a recent move. Thse fit my old rack perfectly.

The company advertises that it fits that metal shelving, They give you the measurements. It’s diameter is too small - it falls right into the metal tubing it is supposed to screw into.

I was concerned the sizing of the connectors would not fit my metal rack from Home Depot, but the connectors fit perfect. High quality.
