they fit perfect and glide across the floor

There are amazing it roll smooth very happy

I had a lot on f problem withe roller wheels on my dolly but once i put these on they roll incredibly smooth

Perfect fit for hard black OEM rollers that left black marks on the white tiles on the bathroom floor. These work great!

These wheels were a huge upgrade over the cheap plastic wheels that came with my chair. It rolls much smoother now. It's also more quiet. Thanks!
