Seasonal adjustment options allow you to swap between window and screen on your door. The SK9 includes all necessary brackets and screws for installation and is easy to install using the existing holes on your door (if this was the model on the door previously). Ideal for doors up to 1-1/4 in thick and 30 to 50 lb. To protect your door and the door closer, a storm chain is recommended (see SK14).
