Andersen Window Sash Balance

Question

This is a double hung Andersen window circa 1987. I need 4 of these.

Additional unrelated question. The lower half moving window is rotting at the bottom. Can I replace that part too, or do I need a whole new window?

Hello! I recommend our 24-939. This can replace all Andersen sash balances stamped with "9#31," like yours.
