Every door is actually composed of 3 basic components. The door slab, jambs, and casings. Doors are hinged on a jamb which is considered an essential part of the door. The jamb is in its turn fastened to a wall opening. The gaps between the jamb and the wall-opening are covered by specific longitudinal elements called casings which create a frame for the door slab. The final elements are the specially designed accessories: handles, the lockset, and hinges.
