Single hung aluminum windows (circa 1977)





Hello, thank you for posting!
I am not positive which series is needed based on your picture so I am going to have one of our senior experts take a look and see if they could recommend a replacement for you. We'll reach out as soon as more information is available. Thank you for your patience.



Hello,
I believe you have a discontinued Keller window that was made in Milford, Virginia. You didn't show the window lock, so compare 90-028 and 90-031 that were used by the manufacturer. If it is, you would need S303-23 where the spiral is approximately 3-5/8" longer than the balance tube. Please confirm that the length of the tube is 23". Other parts are,18-002 top sash guide and bottom sash clips,17-018 / 17-019.
