7/8" shoe

We can absolutely make this balance for you, though it will have to be a custom order since it's not a stock configuration. If you were interested, can you just tell me how many you needed?

One thing to note is that we will be using the 2820 stamp, not 28B. This indicates a spring that can carry 12 through 16 pounds. I'm pretty sure your sash weight will fall under that range but you may want to double check just to be sure.

Great, so what I'll do now is email you a purchase link that will allow you to add 4 of these custom balances to your cart. You can then add anything non-custom you need, such as the glazing bead, to your cart as normal. That way you can checkout with everything altogether.
