Window channel balance

Thanks for reaching out! I'm confident we can recommend a replacement for your balances. Although, I will need to see a photo of the top attachment to determine the correct replacement.

The stamp tells us the weight range a pair of balances may be able to support but we cannot use it to identify the series.

Please let me know if you have any questions.

Thanks for the additional photos. Your window balances can be replaced with either the S351-34 or the S390-34. To determine which series you have, measure the depth of the bottom shoe.

Our 3340 stamp will support 23 to 28lbs.
