Cross-line laser levels offer the highest value of any type of laser: they're extremely versatile and easy to use. Johnson's self-leveling cross-line laser features GreenBrite technology, making the beam 400% more visible than red beams for working in sunny or brightly lit conditions. It projects two crisp, clean laser lines simultaneously - one vertical and one horizontal. It also features a manual mode for use at any angle for working on stairs or other non-level projects. Thanks to the laser's visual out-of-level indicator, you'll never need to worry about accuracy - if the laser can't self-level, it will alert you by flashing the beam. Versatile tool is useful for any number of leveling projects, such as hanging shelving and pictures, tiling walls, leveling cabinets, finish work, flooring, drywall track/stud wall installation and more. Includes Laser, magnetic target, magnetic bracket, glasses, 2AA alkaline batteries, and hard-shell carrying case.
