Installed in Flowery Branch, GA, this Amarr carriage tamp garage door has arched windows to complement the opening. Instead of a 90-degree corner, we have a 45-degree or a dutch opening. The garage door was installed because the door we replaced was an old wood garage door that had rotted. We also installed a new LiftMaster 8355 belt drive opener. The door shown is a three-layer insulated garage door also known as a sandwich garage door.
