Thanks for reaching out! There are not an extended-travel channel balance but they will still need to be a custom built assembly.
You have either the S380-44 with a 1" shoe or the S385-44 with a 1-3/32" 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. Let me know if it does not match either measurement.
Comparison of the S378, S380 and S385 balance shoes.
