Glass grid doors – also known as mullion doors – bring to mind a past era of detailed glasswork and fine cabinetry. Our glass grids can hold multiple small panes of glass, or they can simply give a larger, single pane the appearance of being split up into multiple frames. The design options are limitless, from delicate lattices to strong, straight lines. From kitchen cabinets to doors on china cabinets to specialty bookshelves, mullion doors are available in countless patterns and finishes sure to enhance the appearance of any room designed with the classical in mind.
