Rail and Stile construction at its most basic consists of five members: the panel and the four members which make up the frame. The vertical members of the frame are called stiles while the horizontal members are known as rails. A basic frame and panel item consists of a top rail, a bottom rail, two stiles, and a panel. This is a common method of constructing cabinet doors and these are often referred to as a five piece door.

In larger panels it is common to divide the panel into one or more sections. To house the extra panels, dividing pieces known as mid rails and mid stiles or muntins are added to the frame.

Muntin or Muntin bar is a strip of wood separating and holding panes of glass in a window. Muntins are also called "glazing bars", "muntin bars", or "sash bars". Muntins can be found in doors, windows and furniture, typically in western styles of architecture. Muntins create a grid system used to divide small panes of glass, called "lights" or "lites", into a single window sash or casement.

Windows with "true divided lights" make use of thin muntins in residential windows, positioned between individual panes of glass.
