I submitted my inquiry on your contact us link before I saw this link!
I have removed the balance from my Peachtree double hung non tilt window and there are no markings on it. Approx 1988.
The balance measures 32 1/4". The window is 40" x 70". The lower sash weighs 21 pounds.
Your chart recommends the 31.25-3 balance. However, other online resources state this balance would fit the D2472 window. My window appears to be a D4272 which the other sources state requires a 31.25-6.
I am totally confused! Which balances should I purchase ?
Thank you,
Paul
