Abstract
A tool for projecting a visually perceptible plumb line extending from a proposed location of a fire sprinkler head on a suspended ceiling. The tool includes a base and a self-leveling laser. The base is configured and arranged to supportably engage the support beams of an installed suspended ceiling grid system so as to support the tool when placed within a panel-retention frame of the installed grid system. The self-leveling laser is repositionably mounted on the base with a vertically extending laser beam which is plumb when the laser is level.
