Non pull out window rails

Hello,

We can supply your replacement balances but it will need to be a custom order due to the length, extended travel pulley system and unique combination of end attachments. To get started, we'll need to see another photo of the side of the bottom fitting as shown in your first photo without the tape measure. We'll also need to know the numbers on the metal channel. Lastly, we'll need to confirm the number of balances that you need, with the minimum being two. Thank you!
