Hello,
This is a SWISCO Series 390 balance. Please check on the length of the balance, exclude fittings for this measure, I believe it may measure 31". Next, we need the weight of the window sash. Please remove the window sash and place it on a scale to get us the weight in pounds. |

You were correct, it was 31" and the weight of the window sash was 25 lbs.

Thank you.
It seems your replacement will be the S390-31 Channel Balance, with the 3040 stamp. |
