| 主权项 | 1. An elongated stabilizer bar for maintaining a pair of grid runners in parallel upright positions to support a panel on respective grid runner support surfaces, the stabilizer bar having a horizontal leg and a vertical leg, the horizontal leg having self-penetrating tabs arranged to pierce and thereby grip a core of the panel to fix the stabilizer bar to the panel, the vertical leg having a vertical slot at each end, the slot having an open bottom, the slot having a horizontal width adapted to receive and confine an upper reinforcing bulb of a respective one of the pair of grid runners in an installed position to thereby restrain the respective grid runner against excessive bowing and twisting deflection and permit the stabilizer bar and panel to be freely and simultaneously lifted from respective installed positions for access to a space above the grid runners. | ||
