Thanks for the research efforts Paul. I think that part may work for my needs IF I can remove the old rollers from the window. The window is used in a wet location and the screws holding the rollers are in bad shape. One screw head twisted off when I tried to remove it. If I can ever get them out, at least I know I can obtain a replacement.
Thanks again! Tony
No problem, Tony. Let me know if you have any other questions or concerns.
