Old window balance

Thanks for posting! The balance retainer appear s to be our Yale Stop part 16-028. These are typically sold with our Series 351 and Series 390 Balances. Although, it is difficult to tell because the top attachment of your balance is damaged.

With that said, you balances appear to be either our S351-24 or S390-24 Channel balances with a 2320 stamp option. To confirm the correct replacement you'll need to measure the depth of the bottom shoe on your balance. You may use the diagram below for reference.

Comparison of the S351 and S390 balance shoes.

If your attachments do not match those on the these two series, please let me know.
