Thanks for writing in. Take a look at our 23-070. Look over the dimensions and specifications and see if this matches what you need. If you wanted a ball-bearing version of this roller, see our 23-086. Both these rollers have concave wheels. I believe this is what you have, but it's hard to say for sure from your photos. If your roller by chance had a convex wheel instead, take a look at our 23-081 instead. |
