Abstract
Mobile home ceiling boards are normally made in 4-foot-wide sheets which are fastened to the ceiling roof trusses at 16-inch intervals. Herein are shown at least three separate ways of fastening the ceiling board to the roof trusses by the use of a fastening means which engages the back of the ceiling board and is fastened to a roof truss member. This permits the utilization of a concealed fastening structure for fastening the large ceiling boards to the roof trusses of a mobile home ceiling or any other conventional ceiling structure. Each of the three fastening techniques involves the use of cuts in the ceiling board which receive the flanges of a fastening structure. This structure can be previously attached to the roof truss or installed in the board cuts before attaching to the roof truss. A combination system could also be used wherein a part inserted in the board cuts would mate with a part previously attached to the roof truss.
