If your windows originally used spiral balances, it's probably best to stick with them. If you have older wood windows, I think our Series 500 is a safe bet. Our company has been using these on old wood windows for the better part of a century. You would also need a clip on the end like the 17-012. See what you think! As for the parting bead, I don't know what to recommend. You could have about anything, and without a sample to go off of there would be no way to know for sure. |

The overall sash height isn't the best method to determine length. The rule of thumb is to get the height of the visible glass and then add 1" for the top sash and 3" for the bottom sash. For example, if the height of the visible glass on the bottom sash is 20", you want a 23" long balance; if it's the top sash, you'd want a 21" long balance. If it's not an even inch, round up. |
