Need replacement sash balance modules for Andersen double hung window. Both panes are the same size; glass measures 32 1/2" wide X 28" high. Photos are attached showing 1600-17 and 11600A-3. Thank you

Based on your stamp of "1131," I recommend the 24-1133 Andersen sash balance. I believe this will work for your window as a replacement.
