Hello, Based on your photos, I agree that you could have the S350-34 channel balance, which comes with the 19-002 top and 15-004 1-3/32" deep bottom fitting. As long as those match your original assembly, you'll be good to go. As for your top sash guide, it looks similar to the 18-166 but you'll need to compare the dimensions to confirm. This will be the deciding factor to determine if these parts will work for your repair. Thank you. |
