Quick Learner from Michigan
What sash balance do I need for single hung window? Both windows slide up and down but not forward. Enstalled 1989.

Hi- thanks so much for posting! 

We will need to see a photo of the sash balance if possible. Please show us all the stamps that are located on the balance. This will help us to determine what replacement will be best for you. Thanks!
