Hello, We believe you have a cottage window where the top sash is shorter than the bottom sash. Based on the stamp codes in your photos, it looks like you need the 24-L9-1327 for one side and 24-R13-927 Andersen sash balance for the opposite side. Be careful when replacing them that you don't mix them up since one cord is shorter for the top sash. Thanks for posting! |
