IMPROVED CEILING RUNNER A B S T R A C T A ceiling runner comprised of an elongated generally U-shaped channel member having longitudinally spaced openings in its web, each with one end portion shaped and sized to confine a transversely arranged upright C-stud therein. The remainder of the opening is of such size and shape as to permit the c-stud to be initially inserted therethrough with the web of its cross- section extending longitudinally of the web of the channel member and to be thereafter twisted about its longitudinal axis to a relatively transverse position to snap into place within said end portion, the web of the channel member having a retaining tab at one side and a detent and camming surface at the opposite side of the opening to cause the C-stud to flex sufficiently to snap into said end portion and to retain the C-stud within said end por- tion once it has snapped into place. In addition, the channel member has outwardly extending trim flanges at the free ends of its legs which extend beyond the wall-board only in a single plane parallel to the web and have no depending structure, so as to provide an acoustical angle appearance and a finished look along the line where the upper edge of the wall meets the ceiling.
