Abstract: A suspended island ceiling system is disclosed in which conventional grid runners are interconnected to produce a rectangular grid. The grid defines openings in which ceiling panels are supported. The grid includes perimeter runners and inner runners which connect at their ends to the perimeter runners at spaced locations along the length of the perimeter runners. Channel-shaped border members are supported on the perimeter runners and provide a finished edge appearance for the island. The border members provide an outer vertically extending base wall and vertically spaced, horizontally extending legs. The upper leg extends over the adjacent perimeter runner and engages the upper surface and one side of the bulb thereof. The lower leg extends along the lower side of the perimeter runners and engages the lower side and at least one side of the flange of the perimeter runners.
