Identification

Thank you for reaching out to us! Take a look at the S380-29, S385-29, and S378-29. The difference between these parts is the depth of the bottom shoe. You'll have to measure as shown below to determine the best match.

You will also need to weigh the window sash on a scale to determine the correct stamp option. There's a chart under the product description on our balances' store pages that you can use as a reference for what stamp to select.

Please let us know if you have any questions.
