ABSTRACT:
A device for leveling and squaring which includes a level body having a spirit vial or electronic inclinometer, wherein a battery powered laser module assembly is rotatably mounted in one end of the level body for emitting a visible laser beam therefrom. The level body contains a transparent window which allows the laser beam to exit therefrom. Further, the level body has a groove parallel the longitudinal axis thereof to provide a horizontal (0.degree.) reference line. Wherefore, the laser beam establishes a precise line, which is variably adjustable from horizontal (0.degree.) to 90.degree. thereto, for alignment and squaring uses. Magnetic strips are used for attaching the level body to ferromagnetic materials.
