Tilt Window Channel Balance Help

A quick learner from Florida says:

Looking for a channel balance as shown in photo.

20" channel balance for a PGT series 2200 single hung window.

Just to clarify, the PGT window is a tilt out window for easier outside pane cleaning. The only stamp I see on the metal channel is "20D". Plus, a smaller stamp next to it that is "BSI" and also "TN"?

Thanks for posting. This resembles our S770-20, with a 20D stamp option; but instead of the clip that comes with our standard version of this balance, it has the 15-044 Attachment instead. No worries however, as we'd be happy to custom build these for you. I am sending you an email with a custom link to order (2) of these custom balances. Let me know if you need a different amount, or have any questions prior to ordering. Many thanks.
