HI AGAIN,
1.- KITCHEN WINDOW: The 11 A/W 72 XI is written on window sash.
window sash measures (L)361/2" X (W) 361/2".
2.- Bedroom Window: 6-69 is written on GLASS OF WINDOW SASH; Window Sash GLASS measures :(L)16" X (W)201/2".. I believe the correct size of window would be 3032. Can you help me find out the correct Counter Balancers for booth windows. Thanks again for any help. Joe Murphy

I tried working with an Andersen contractor to figure out which boxes you need but it is not easy. He could not figure out your 36" x 36-1/2" and he is not positive about your 20-1/2" x 16" window (he believes that one might be our 24-531). You will need to provide the numbers stamped on the box to get definite recommendations to which replacement boxes you need to order.
