Good Afternoon,
Very nice pictures, I have them marked for review by a window expert here. Quick question though, can you respond back here with the stamp that you should be able to find on the metal channel (it may be a little faint). The stamp helps us to determine the strength of the replacement balance you will need. |

Hi,
Looks like a 29" Series 390 Balance, with the 19-002 Top and 15-001 Shoe attached. A 28 3 stamp normally translates to 2830 To check, remove the window sash and place it on a scale. The 29" Series 390 with Stamp Option 2830 will carry a window sash weight range of 16 through and including 23 pounds. This information is based on 2 balances per sash. Balances are designed assuming friction in the jamb weather-strip will carry a portion of the sash weight. Suggested sash weights are approximate. |
