105 Nickerson Window

Thanks for reaching out to us. This balance appears to be a match for our S770-24, but I'm not familiar with that stamp at all. My recommendation would be to weigh your sash on a scale and then refer to the chart on the S770-24 store page to see if any of our more standard options can support it.

If your sash weight exceeds the listed options, just let me know and we can work from there.
