Abstract: A cabinet door construction wherein a panel is floatingly received in a seat formed in a generally rectangular framework forming a central opening blocked by the panel. A suitable retainer attaches to a front face of the framework for retaining the panel in the seat provided therefor in such a manner that the panel may expand and contract without cracking as humidity conditions and the like vary. The framework includes a plurality of rails arranged in a pair of substantially parallel sets disposed perpendicularly to one another and rigidly secured together by fasteners comprising a pair of parallel legs connected together by a web and driven into the abutting ends of adjacent rails so as to lie substantially in the plane of the framework.
