Anderson sash balance choice
A home owner from Chevy Chase, MD says:

I'm replacing the sashes on a double hung Anderson window. The visible glass size on each window is 24.5" wide by 22" tall. The current sash balance is marked H19 725, and 11600-17. I am having trouble determining which is the correct replacement part.

Good morning, and thank you for posting! Please take a look at our 24-737 Andersen sash balance, which can be used to replace balance boxes with the stamp 725.
