Balance

Hey there,

Thanks for writing in! Your balances look like they could be either the S380-31 with a 1" shoe or the S385-31 with a 1-3/32" shoe. The metal channel of these balances is 31".

To determine which series is needed for your window, look over the dimensions from the diagram below to confirm the depth of your bottom shoe. Let me know if it does not match either measurement.

Comparison of the S380 and S385 balance shoes.

I am unable to cross-reference your stamp, unfortunately. With that said, you'll need to obtain the exact weight of your sash to determine the stamp you need. Once you've confirmed the series, you'll find a chart below the product description of the balance, on our website. The options are listed according the weight range that option can support.
