Good question. For your Marvin Window, you should be able to use our S751-37 channel balance with a 36TG option that holds a sash weight of 29-38 pounds. Compare your balance to ours to see if it is a match. If not, upload a few detailed photos of your balance and we will take closer look for you. If you should also need some guidance on installation, take a look at the media guides we placed on this page. |
