Balance for bottom sash, 26C BSI

Question

Hi,
I'm trying to replace a channel balance for a lower sash. It's a double hung vinyl window weighing 17.4 lbs and 26" wide. The steel channel is stamped "26C B.S.I. NK", is 26" long, and was part of a ModernView window (circa 2000). I believe the balance distributor was Balance Systems Innovators and the balance manufacturer was Amesbury Truth. It may have been a Series 777 balance. Do you carry that part and what is the cost and delivery time?
Thanks

Hey there,

There is a chance that we can supply you with a replacement channel balance for you window. However, to determine the correct replacement balances needed for your window, 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.

Let me know if you have any questions.
