channel balance part number

Thanks for reaching out to us! I am confident we can supply you with a replacement for the channel balances you have here but I'll just a few more details to confirm the correct replacement. To start, may I please see a clearer photo of the pulley system in the center of the balance where the string and spring meet?

Please feel free to reach out with any questions you might have.

Thanks for the photo! Your balance can be replaced with either our S380-26 with a 1" shoe or our S385-26 with a 1-1/2" shoe. To determine which of these is the correct replacement, confirm the dimension for the depth of your shoe.

I'm not able to cross-reference the stamp on your balance, unfortunately. That said, you'll need to obtain the exact weight of your sash to confirm the correct stamp option. There is a chart below the product description of the balances that lists the weight range each stamp option can hold.
