Transoms provide beautiful detail to interior doors. Our transoms are single pane 3/16″ annealed glass (1/4″ tempered glass also available) with simulated divided lites. Grille bars types include 1-1/4″ primed poplar, 7/8″ primed sapele, or 1-1/8″ PVC with flat profile (Shaker-style). Standard or wide stiles available in direct set or sash in frame. Interior trim will match the door unit. Please specify if transom grilles need to align with divided lites on the door.
