window balance

Hi there!

Thank you for reaching out to us. Your balance looks like it may be a match for the S380-29, S385-29, or perhaps the S378-29. The difference between these parts is the depth of the bottom shoe. You'll have to measure yours as shown below. 

There should also be a stamp printed on the back of the metal channel. Can you confirm?
