Abstract: A factory molded, manufactured light well, or chase way, for a skylight includes sides, a flange, and ledges. The light well is made from such material as fiberglass, plastic, arcylic, dense styrofoam, or other such moldable material. The sides form the light well proper. The flange is of a single molding with the sides; forms the base, or lower edge, of the sides; and flares perpendicularly outward from the interior of the light well. The flange provides the means of finish trimming the edge of the box framed hole cut in the ceiling immediately below the skylight. The means of attachment to the box framing of the ceiling hole consists of ledges, of a single molding with the sides. The ledges protrude from the exterior of the sides and parallel the flange around all the sides. Under these ledges, standard framing lumber can be placed and secured to the box framing, thus rigidly attaching the light well to the ceiling and its framing.
