Phillips window sash channel help

A home owner from Grass Valley, CA says:
The channel is 1/2" wide and 26" long. It has the number 2530 BSI stamped on it (see photos) I need help identifying replacement for this.

Hey, thanks for posting. I've narrowed this down to two possible channel balance Series: either our Series 351 or our Series 390 balances.

Now, as you can see, there is only one difference between these two Series, and that is their bottom shoe. The Series 351 uses the 15-002 while the Series 390 uses the 15-001. I can't quite tell what you have based on your pictures, though. Please carefully compare their dimensions to your own hardware and see which is a better match.

A home owner from Grass Valley, CA says:
Thanks for the guidance. Based on measurement, it looks like the 15-001 is the winner. Can I assume the stamp of 2530 on my channel is the sash weight range option I should choose when ordering the part?

Thanks again,

Yes, the stamp printed on the balance corresponds to our list of options.
