Thanks for reaching out! The channel balance you have looks a lot like either our S351-14 with a 1" shoe or the S390-14 with a 1-1/8" shoe. 

To determine which series is needed for your window, look over the dimensions from the diagram below to confirm the depth of your bottom shoe. 

You'll need to select the 1330 stamp.
