Hello! Yes, you want to replace both balances at the same time. See our S385-14 to start out and see how well out information matches up to your balance.

Hi, You most likely need the S385-14 with 1330 stamp option. To check, weight the window sash.
A 1330 stamp will carry a window sash weight range of 9 though and including 11 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. |
