Silverline balance

Question

I need to replace a couple balance units on my silverline windows. I have a picture of the stamp on the original balance. Can you tell me which unit I need to order?

Thanks,

Matt

Hello, Matt. I'm not sure what you have, unfortunately. 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, we 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. We will also need to know the dimensions of these fittings.
