The number on my balance is 2040




We have dozens of different balances with that stamp. It's not a product code or anything, it just indicates the strength of the spring.
In order to figure out what Series this is, I need you to remove an undamaged version of this balance from the window and show me clear pictures of the top and bottom nylon fittings. I will also need to know the dimensions of these fittings. The video below will go into more detail.

I need 4 balances they are 22 inches long and 1/2 inch wide. Thanks marie



Thank you so much, Marie. Based on what I see here, you have either our S380-22 or S385-22, depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match.
Also, the top fitting looks different on ours, but that should be fine. I'm more concerned about the bottom shoe.


Hi Tom The bottom shoe is exactly 1 inch. So I have the S380. I would need 8 not four. How do I pay? Also I have another window which needs balances. Its the same manufacturer as the previous ones. They are 21 inches long and 1/2 inch wide. The bottom shoe is exactly 1 inch also. I would need 4 of those. I am attaching photos. Thanks Marie
