Even though I ordered the wrong size it was priced well and arrived quickly.

Perfect fit! Thank you, my husband was able to put the shelves together again. We are so happy!

Fit loosely, difficult to get threaded correctly. Hold good enough for a light to medium load, but wouldn’t try to load to the shelf max weight

We bought these to put together to standard NSF shelves. This was the one part that for years was hard to find. Search over. The part works like the original: good fit, solid construction, with clean threads.

I lost one of these in a move and thought, "No worries, I'll just order another from the company that made it." They charge $5.00 or more for one. Nope! Fortunately I found these. They are strong, thread in easy, and now I have extras. I expect they will work with any brand of metal shelving that have 1" pipes.

This product was not 1" and didn't fit my Home Depot HDX shelving-unit poles. They were too small and dropped right in rather than screw in.

The picture shows a Seville Classics connector on the left and this connector on the right. Seville Classics uses a fine pitch thread, these connectors are not fine pitch.
