59. DOOR COMPONENETS

When framed in wood for snug fitting of a door, the doorway consists of two vertical jambs on either side, a lintel or head jamb at the top, and perhaps a threshold at the bottom. When a door has more than one movable section, one of the sections may be called a leaf. See door furniture for a discussion of attachments to doors such as door handles and doorknobs.Lintel - A horizontal beam above a door that supports the wall above it. (Also known as a header)

Jambs - The vertical posts that form the sides of a door frame, where the hinges are mounted, and with which the bolt interacts. till - A horizontal beam below the door that supports the frame Doorstop - a thin slat built inside the frame to prevent a door from swinging through when closed, which might break the hinges. Architrave - The decorative molding that outlines a door frame. (called an Archivolt if the door is arched). Called door casing or brickmold in North America.

Door furniture or hardware refers to any of the items that are attached to a door or a drawer to enhance its functionality or appearance. This includes items such as hinges, handles, door stops, etc. This is known as a 'breakaway' feature. Pushing the door outward at its closed position, through a switch mechanism, disconnects power to the latch and allows the door to swing outward. Upon returning the door to the closed position, power is restored.

Panel doors (doors built with frame and panel construction, also called stile and rail doors)Stiles - Vertical boards that run the full height of a door and compose its right and left edges. The hinges are mounted to the fixed side (known as the "hanging stile"), and the handle, lock, bolt, and/or latch are mounted on the swinging side (known as the "latch stile"). Rails - Horizontal boards at the top, bottom, and optionally in the middle of a door that join the two stiles and split the door into two or more rows of panels. The "top rail" and "bottom rail" are named for their positions. The bottom rail is also known as "kick rail". A middle rail at the height of the bolt is known as the "lock rail", other middle rails are commonly known as "cross rails".
