Part number identification

Thanks for posting. Unfortunately, that stamp does not help us identify what balance you need. The stamp is merely indicative of the balance's strength, and it is not a serial number of any kind.

To help us identify the correct replacement hardware for your application, please remove the balances from your window and take a few pictures of them, and then reply back to this thread with the images attached.

Please make sure you take a picture of the attachments on both ends of your balance. Also, be sure to include the length of the channel portion of your balance in inches. Do not include attachments in your measurement.

Thanks for posting! I completely agree. Based on the size of your bottom shoe, then I think that our S380-27 is a good guess. The top attachment is easy enough to identify, and it matches the 19-005. I'd also recommend the 2630 option. Make sure to compare that weight rating to your own sash weight to make sure it will work!
