In the tile mode, one flange is used as a tile separator and the other flanges are used respectively to support the trench cover and an edge of the floor tile. In the carpet mode, the trim is turned 180 DEG so the tile separator flange is inactive wile the other flange respectively support the edge of the floor tile and the trench cover. In the tile mode, the edge of the floor tile has vertical support so the breakage is avoided.
