Thanks for posting. I am confident that we can supply you with a replacement channel balance you need. However, to determine the correct replacement, I'll need to see a photo of an undamaged balance removed from the window. Unfortunately, the stamp from the balance does not indicate the type of balance you need. It only tells us the weight range the balance should be able to carry to support the weight of your sash.

To properly identify them, I'll need to see a photo of any attachments that may be on the top or bottom of the balance.

If this is a tilt window, I'll need to see any attachments that could possibly be left behind in the window or that could possibly be attached to the bottom of the window. If there is a hook at the top of the balance, I'll need to see the space in the window channel where the hook connects.

Please feel free to reach out with any questions you may have.

Thanks for the photos. Your balance appear to be our S395-27 with a winged top and a wingless bottom shoe. You'll need to select the 2640 stamp.
