This Craftsman knotty alder double entry door pairs a 6-lite True Divided Lite (TDL) design with three raised lower panels with a clean, considered profile, making a warm, confident first impression at your entry. The door is built from knotty alder, a warm, characterful wood whose natural knots give every door a one-of-a-kind, rustic personality. The glazing fills the space with natural light without sacrificing the door's solid, substantial feel, and the energy-efficient Low-E glazing helps hold comfortable temperatures and lower heating and cooling costs. Inside, an engineered laminated veneer lumber (LVL) core and engineered stiles and rails work together to deliver strength, stability, and resistance to warping over the long term. Available unfinished and ready for your own stain or paint, or choose a pre-finished door that arrives ready to install.
