It's tough to tell what you have while it's still installed, but I made a list of potential replacement parts on this page for you to review. We have detailed dimensions and photos on each of their respective store pages. That said, you will need to remove your roller from the patio screen to match it up at the end of the day. It also looks like your is corroded, so you might want to consider the 84-101 nylon roller with the stainless housing to stat out. |
