Fig. 179 shows a method of trimming doors: a is the door-stud; b, the lath and plaster; c, the ground; d, the jamb; e, the stop; fand g, architrave casings; and h, the door-stile. It is customary in ordinary work to form the stop for the door by rebating the jamb. But when the door is thick and heavy, a better plan is to nail on a piece as at e in the figure. This piece can be fitted to the door and put on after the door is hung; so, should the door be a trifle winding, this will correct the evil, and the door be made to shut solid.

Fig. 180 is an elevation of a door and trimmings suitable for the best rooms of a dwelling. (For trimmings generally, see Sect. V.) The number of panels into which a door should be divided may be fixed at pleasure; yet the present style of finishing requires that the number be as small as a proper regard for strength will admit. In some of our best dwellings, doors have been made having only two upright panels. A few years' experience, however, has proved that the omission of the lock-rail is at the expense of the strength and durability of the door; a four-panel door, therefore, is the best that can be made.

302. - Hanging Doors

Doors should all be hung so as to open into the principal rooms; and, in general, no door should be hung to open into the hall, or passage. As to the proper edge of the door on which to affix the hinges, no general rule can be assigned.
