DL303 has four individual columns of louvers giving it a charming look and providing plenty of space for air to flow freely between the louvers of the door. This Dutch door design can be made to any size. We custom craft each door to fit your opening. Jamb widths can be adjusted to meet your wall thickness requirements. We often make jambs in excess of 10 inches wide. Slab doors can also be purchased in which case we can make the doors 1 3/8 thick if your door jamb is setup for a standard interior door. Our standard interior doors are more substantial 1 ½ thick. Exterior designs are mainly 1 ¾ and up to 2 ¼ thick if your door is oversized. Tops and bottoms can always be mixed and matched to make the perfect Dutch door for you home and we can accommodate many other custom requests. Allow us to help design the door of your dreams.
