Thank you for your review. We apologize for the inconvenience that you have experience with the sill adapter, but we are happy to learn you are satisfied with your purchase. The LuminAire Retractable Single Screen Door really comes with a 30-1/2” sill adapter. That is how the door was packaged. If the customer wants to install a longer sill adapter, the part is available for purchase. Rest assured that we will create a feedback about your comment. Should you need assistance about your screen door, please contact the Andersen Solution Center at 1-844-813-6664. - Noel
