The Craftsman slab interior door is a popular design. It reflects the unadorned, aesthetically balanced style created more than a century ago. With its clean lines, flat panels and smooth surfaces, this molded interior door is the perfect choice for traditional home door replacements or new construction. A slab is a blank slate, it does not have hardware or hinge cut-outs. Upgrade to a solid core option to help reduce sound transmission between rooms and to meet fire ratings.
