Hinged Doors
 |
While hinged doors come in many types, most
have the same basic framework that consists of two stiles that run
vertically and two or more rails that run horizontally. The hinges are on one stile (the hinge stile); the latch and lock are on the other (the lock stile). Panel door have several panels mounted between the rails and styles. Flush door have an insulation core or filler material between the rails and styles and a veneer that overlays the entire assembly. Most hinged doors are attached to their frames by two or three hinges. The frame consists of jambs, casing, stops, sill, and threshold. The jambs form the sides and head of the frame; the casing acts as trim and as support for the jambs. The stops are wood strips against which the door fits when closed. |

With exterior doors, a sill fits
between the jambs, forming the frame bottom. The threshold (also called
the saddle) and weather stripping are fastened to the sill.
For security, an exterior
door's latch plate should be mounted with screws that are at least 3
inches long so the jamb can't be shattered for easy entry. |
