Thanks for posting, Jack. Did you have spiral balances installed originally? If not, please double check to make sure you have enough room to install one. If so, our Series 500 is a good choice. It has been used on wood windows for decades.
As for the length, please give me the width and height of the visible glass on each sash you are looking to replace. Knowing the size of the visible glass will help us determine what length you need. Please also give me the weight of each sash so that we can recommend the appropriate tip color. |

Hey, Jack. Thanks for your patience in this matter. For a glass height of 27-5/8", I recommend our use S500-29 for the top sash and S500-31 for the bottom sash. For sashes up to 30 pounds, use the red tip. You will also need our 17-012 bottom balance brackets to attach to the sash and a charging tool like our 75-004 or 75-005. Let me know if you have any other questions!

Thanks! For Window 1, I recommend a 35" long balance and for Window 2, I recommend a 32" long balance.

Sure!, for Window 1, the top sash will take a 35" long balance and the bottom sash will take a 37" long balance. For Window 2, the top sash will be 32" long and the bottom will be 34" long.
