Exactly what I needed
My bi-fold closet door hasn't functioned properly since I moved in. After a bit of YouTube research, I discovered that I needed to replace this part. It was a breeze to order online, have it shipped to my house, and switch it out for the broken part. I was also able to bundle this wheel part with a metal brace for the bottom of my door, since that was broken as well. These parts were easy to find and easy to install and my door is working great now! I will also note that I had gone to the hardware store initially, but would have had to buy a complete set of door hardware and spend twice what I needed to because of needing to buy extra parts that I didn't need. I pulled up this product and ordered online while standing in the store because this was the best value for my money.

Perfect for our closet doors
Has one broken wheel and found this one which was a perfect fit. Now have an extra one for future fixes. I recommend.

Does what it’s designed to do
The original one on the top of my bi-folding door in my bathroom snapped (well, the plastic the guide wheel snapped), door would no longer open nor close! I actually didn’t know what that part was called but, after a bit of word and phrase guessing finding it’s called a “bi-fold door top guide roller” I found this on Amazon. Easy to fit and does the job well! I’d recommend it
