Window Balances 2990EG B.S.I. 32

Handy Person from Gainesville, FL
I need to replace a pair of balances on one window.
It has never worked since we moved in.
As seen in the photos, they are 30" long, stamped with 2990EG B.S.I. 32
In the photos showing the end attachments, it shows both balances side by side.
Please help me figure out the correct balance for my window.

Thanks for posting! I can help you find a good replacement that will actually work in your windows.

I'll need some more information. First and foremost, I will need to know the weight of your window sash. That will help us determine the appropriate option.

I will also need to know what bottom shoe you have, exactly. Please look at the measurements for our 15-001 and 15-002 bottom shoes and note their depths. As you can see, they are 1-1/8" deep and 1" deep, respectively. Which measurement more closely resembles your own shoe?

I placed a table with a shipping scale on it, and lowered the sash onto it (I hope this give an accurate reading) and it weighed in at 35lbs.

15-001 is the bottom shoe which most closely resembles the one that I currently have.

Great! Based on your specifications, take a look at the S395-30 with the 2965 option. Two balances with the 2695 option can carry a window sash weight range of 35 through 39 pounds.

Tom,

Does this mean that the balances which were in the windows until now were rated too high? Or will these new 2965 balances not perform as well?

Looking at the original stamp on your old balances, I believe the capacity was for a 32 pound sash.

Now, the 2965 is designed to hold 35 through 39 pounds, so these new balances are stronger. We can go lower if you prefer, but we recommended the 2965 option based on the fact that your sash weighs 35 pounds.
