Sash

A frame — typically wood or aluminum — that holds glass panels in a cabinet door. In cabinetry, the sash is the grid framework inside a glass-front door that divides the glass into smaller panes or supports a single glass panel. Sash profiles vary from thin, delicate muntin bars to heavier mullion frames, and they can be designed in square, arched, or diamond patterns to match the kitchen's architectural style.
