Hinge: A hinge is a component that attaches one edge of a door to the frame, while allowing the other edge to swing from it. It usually consists of a pair of plates, each with a set of open cylindrical rings (the knuckles) attached to them. The knuckles of the two plates are offset from each other and mesh together. A hinge pin is then placed through the two sets of knuckles and usually fixed, to combine the plates and make the hinge a single unit. One door usually has about three hinges, but it can varyThe main types include: Barrel hinge, pivot hinges, butt/ mortise hinges, case hinges, continuous hinges or piano hinges, concea,ed hinges, butterfly hinges or parliament (UK) hinges, flag hinges, strap hinges, H hinges, HL hinges.

The main parts of the panel doors are:


Stiles: Vertical boards that run the full height of a door and compose its right and left sides. The hindges are mounted to the fixed side (known as the "hanging stile" or "hindge stile"). The handle, bolt and/or latch are mounted on the swinging side (known as the "latch stile" or "lock 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".

Mullions: Smaller vertical boards that run between two rails, and split the door into two or more columns of panels.

Muntin: Strip of horizontal or verticla, wood or metal, members, separating and holding panes of glass in a window or door. Mullions also divide the door into smaller panels.

Panels: They are boards that fill the space between the stiles, rails and mullions.
