Muntin

A thin bar of wood or metal that divides a glass pane into smaller sections within a cabinet door, similar to mullions but typically referring to the lighter, thinner dividers in true divided-light configurations. Muntins create a grid pattern that adds traditional architectural character to glass-front cabinets and can be functional (separating individual glass panes) or applied decoratively over a single sheet of glass.
