We will first need to see the original balance to dentify the proper replacement balance series. Please post some images of the original balance system.
Next, we need the length of the original balance (exclude fittings for this measure). Finally, we will need the stamp numbers off the original balance or the window sash weight in pounds. To get the sash weight remove the window sash and place it on a scale. ANSWER: 15 pounds If you are certain you have a 15" Series 350 balance we can have 1450 stamp options made. *A 1450 will carry a window sash weight range of 13 through and including 17 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. |

The replacement window balance you need is our S350-15 with the 1450 option. Let me know if you have any further questions.
