Yes, you usually always want 2 channel balances per window, 1 on each side. Without seeing your old balances, it will be very difficult to know for sure what you have. You may want to check to see if you have an identical window in the house you can use as a reference.
If not, then going by the picture of your sash I think you might have a Seasonall Nuprime window. These have been known to use our Series 390 balance, but there's no guarantee. If you want to go this route, tell me the weight of the sash and the height of the visible glass so that we can calculate the proper size and strength of the balance. |
