The Timeless screen door is a beautiful design featuring a simple arched radius on the top rail. The T in the bottom is similar to our Old Fashion door and creates added strength and stability for the door along with added screen protection. The door comes standard with a one-piece insert which covers all three openings on the door at once. A two-piece screen setup can be requested which gives you a top insert and a bottom insert. For oversized doors this can reduce the weight of the storm insert panel basically in half and also gives you the option to keep a glass or different type of screen like pet screen in the bottom for added protection against screen damage without losing your view in the upper section.
