Johnson 40-6517 Self-Leveling Rotary Laser System | 29 x 7 in Red | 1 Kit

Overview

The Johnson 40-6517 Self-Leveling Rotary Laser System is built for small jobsites where speed and precision matter. It performs automatic leveling in the horizontal plane while allowing manual leveling in the vertical plane, giving you flexible setup for walls, ceilings, decks, and foundations. An illuminated vertical vial improves visibility in dim environments, and the three rotation speeds (200, 400, 600 RPM) let you tailor performance to the task at hand. Visual and audible alarms help you stay within the leveling range, and a locking compensator protects the inner pendulum during transport.
