Serenity features a ball and dowel spandrel as well as wagon wheel style ball brackets in each corner of the screen opening. The raised panel bottom section makes the door more pet resistant in terms of preventing screen damage and also can be aligned to your entry for fit that compliments the door. A 1-piece screen and storm insert covers the opening on this door which can be easily removed and replaced with a storm panel for winter. At vintage doors we custom make your door to fit your opening so be sure to measure accurately and have us build the door to the size you need rather than have your installer cut it down to size on site. Any adjustment on site should be kept to a minimum. Allow us to do the work for you.
