Window Balance
Hello, thank you for posting,
We can assist with a replacement balance, but to confirm the style you have, we will need to see the inside of the balance where we can view the connection point between the spring and pulley system. From there we can determine the correct series needed to support your window sash. Thank you!
Thank you for the additional pictures!
With this combination of attachments, you could have either an S380 or S385 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment.
The length of the metal channel excluding the nylon attachments should measure 33" long and you will need a 3230 stamp option. Please review and let us know if you have any additional questions!
No problem! Please let us know if you have any future hardware questions.
