I have several windows that use what i can best tell is use the 33" Series 380 Channel Balance Product Code: S380-33. The code on the channel balance is 32 6 FQ cadwell. My problem is this I do not think the balance broke in the sense the string or spring broke but the tension is so high on the window that I have to force the window down and under a lot of tension lock it. Not a very big window probably a standard 27" window in a bay window. It is so hard that it is almost pushes the lock setout of the upper window. Would replacing these with the S3980-33 solve the problem? I like to open them but closing is crazy, Why would they be so hard. The balance spring looks rusted a bit but not broken. Again its closing them not opening. Help!

Sounds like your original balances were too strong. What is the weight of your window sash? You can compare that weight to the list of options we have posted under the S380-33 and find which is the best choice.
