In a fabricated door jamb, the opposite edges of a rib component core of low-grade lumber are faced with strips of high-grade wood, and the face is veneered. Two flange components are fabricated from cores of low-grade lumber, each having one edge finished with a strip of high-grade wood, and their faces are veneered. The flange components are joined to the generally central edge component by tongue-and- groove joints composed of tongues formed on the adjacent edges of the flange components which fit snugly in the grooves in opposite edges of the tongue component, respectively. Each groove is flared and each tongue is tapered complementally so that the tongues fit snugly and wedgingly in the grooves, the tongue-and-groove joints being located so that the backs of the tongue component and of the two flange components are flush and coplanar.
