Window Balancers
Thanks for reaching out to us! There is a good chance we have a replacement balance we can supply you with however, to be absolutely sure I'll need to see a photo of an undamaged balance removed from the window.
I am specifically looking to see a photo of the top and bottom plastic attachments from the balance. The stamp provided only indicates the weight range the balance can carry to support the sash. Unfortunately, we cannot use it to identify the exact series you need.
Also, the stamps are a bit difficult to read from the photos. Can you please type them out?
Please feel free to reach out with any other questions in the meantime.
Given the metal channel, I believe they may be a block and tackle balance. However, to confirm the series, I will need to see those photos.
Once you are able to get them removed, I'll be happy to take a look at the photos as well as any of the other hardware compatible.
Please feel free to reach out with any other hardware repair questions you might have in the meantime.
