The True Divided Lite (TDL) Collection makes a classic addition to any home, complementing a wide range of architectural styles. 1-3/4” thick TDL Collection doors feature individual panes of double insulated, clear, “Low-E” energy efficient beveled glass for beauty, strength and security. True Divided Lite doors have engineered stiles and rails that virtually eliminates warping. Matching 12” and 14” TDL sidelights are available. The Mahogany Collection and Knotty Alder Collection doors that feature true divided lites share the same features as the True Divided Lite Collection.
