When a door shows as in-stock, that means that all of the components for the door are in stock (the slabs, the framing material, etc.). Because of the number of available options (door swing, hinge color, glass, etc.) as well as the size of a completed unit it is not possible to stock them completely assembled. As such, each in-stock door still requires fabrication (framing, etc) just prior to shipping.
A special order door means that the door slabs, glass, etc have to be made per order rather than being held in inventory. The same fabrication steps as above still apply.
The availability/lead time of each door is listed. The lead time listed is the shipping lead time (time in which it is shipped out of our manufacturer's facility), not the delivery lead time. Each unit ships from NC. Transit times will vary based on delivery location, etc.
