Abstract: A grommet assembly for a wall panel and method of installation. The grommet assembly (28) includes a grommet structure (29) for insertion into the aperture (15) made through a wall panel (11) and includes pivotal locking arms (37) for locking at the back face of the wall panel. An insert sleeve (30) provides a circular wall (32) that upon insertion into the grommet pivots the pivotal lock arms (37) of the grommet. The insert sleeve (30) is further provided with snap-engagement members (48) that snap-engage to the circular wall of the grommet so that the grommet assembly is fastened together and to the wall panel. A retention ring (26) may be used prior to cutting an aperture in the wall to secure fabric, or other wall coverings, around the aperture to be cut to prevent displacement or tearing, and to protect the outer wall surface. The method includes the field installation of the grommet assembly from one side of a wall panel.
