This is an older version of our 10-058. They used to manufacture the bottom piece to just be a guide, but in recent years they changed the design to a roller. I know that it looks different but the manufacturer insists that they function the same way and will work as a substitute. I've had many customers report to me that it installed easily and without any issues. See the diagram below for a comparison between the new and old sets. New parts compared to old parts

I'm not quite sure what you mean. Are you asking if you can just replace one roller from the set? If so, you feasibly could but there may be issues later down the line by mixing and matching old and new hardware. To play it safe you may want to replace everything, but it's ultimately up to you. If that's not what you meant, please clarify and I'd be happy to help as best as I can. |
