Extended-Travel Channel Balance Quote

Thanks for reaching out! Your balances do not appear to be an extended travel balance as it does not look like they have a wheel built into the bottom shoe. These balances actually look like they could be either our S380-21 with a 1" shoe or the S385-21 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.

You'll need to select the 2040 stamp.
