The window code on mine is 26c? What will be a good match. So far I know I need a S377-27

26C normally translates to 2630. To check, remove the window sash and place it on a scale.
S377-27 with stamp option 2630 will carry a window sash weight range of 13 through 19 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.
If you are unsure of the balance series you selected, send us photos of your existing balance and we can help you decide the proper balance series.
