Window channel replacement

Hi there!

Thanks for reaching out to us. The number stamped on the balance doesn't tell us the identity, unfortunately. Can you upload photos of the top and bottom fittings? That will allow us to determine what you may have. 

Perfect, thank you! Based on what I see here, I'm confident you can use the S380-27 or S385-27. The best match will depend on the depth of the bottom shoe so you'll have to measure as shown below.

Your old 26 9 stamp is outdated so you'll also have to weigh the window sash on a scale to determine the proper option for your replacements. There's a chart under the product description on the S380-27 and S385-27 store pages that you can use as a reference.

Let me know if you have any questions!

Thank you! You'll want the Series 380 since the shoe is 1" deep. If the sash weighs 36.6 pounds, you can use the 2670 stamp option. A pair of these balances with this stamp will support a sash weighing 36 to 39 pounds.
