<p>A grid ceiling comprising a supporting grid (10,20) with rectangular openings therein, grid panels (30) mounted within said openings. The grid panels may be in the form of grid units including perpendicular hollow interior primary and secondary panels (40,50). The grid panels (30) are secured in place by longitudinally movable clips (60) which engage the carriers, e.g. in apertures or recesses (24). Each clip is slidable longitudinally from a forward position in which can occur and a retracted position in which the tongue is sufficiently within its associated panel to enable the grid panel to be removed.</p> |
