Replacement Window balance
Thanks for the help,
Graham
Hi Graham, thank you for posting,
To further review, we will need to see the balance removed from the window with clear images of the top and bottom nylon attachments. We will also need to see inside of the metal channel where we can view the connection point between the spring and pulley system.
From there we can narrow down the correct series for your window. 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 27" and you will need a 2640 stamp option. Please review and let us know if you have any additional questions!
Thank Again, Cheers
No problem! Please let us know if you have any future hardware questions.
