I have older Anderson windows in my home, Narrowline I believe.
I am looking to replace many of the spring sash balances. The number stamped on one of the balance boxes is D9 7P 27 474. That is for a double hung wood window which is double payned. Measurable glass visible is 28 1/4"W x 20"H top sash, 28 1/4"W x 20"H bottom sash. Are your new Anderson balance boxes interchangeable and which ones would I need. (both balance boxes r & L have the name model number.)
