Hello, the window balance is 12.5" long X 1/2" X 5/8"
It has stamped 12-1 W as you see in the attached photo.
Please let me know which part number should I order.
After searching your website I think that the S377-13 is the correct one.
Please advise!

Thank you,
-John

I agree, our Series 377 looks like our best match. However, if the length of the metal channel is 12-1/2" long, it will need to be custom made.

We can do this for you but before we begin, can you just tell me how many you need?
