Thanks for posting! I agree with your assessment, our Series 350 balance and 18-073 shoe look pretty close. Just double check the dimensions to make sure they're the same.
I would also check the nylon attachments on each balance just to make sure they're all the same. Looking at your pictures, it seems like a few have bottom shoes that don't match the 15-004, as they are missing the wings. However, it's hard to tell. If you have a lot of windows with a lot of different sized balances, then there may be a few oddballs in there. Just keep that in mind. To determine sash weight, you simply have to remove the sash and place it on a scale. Any common bathroom scale should do. Check out the video below to see how we remove this kind of window sash. We do ship to Canada. Check out our Shipping Policy for more information. |

For these kind of balances, you look at the weights listed for each option assuming both balances will be carrying that weight. You do not split it in half.
