The MILWAUKEE USB Rechargeable Green 3 Point Laser is powered by REDLITHIUM USB, delivering all-day runtime and uncompromised visibility. The high-intensity laser beams allow the green points to be visible up to 150' for fast, accurate point transfer. The Integrated Adjustable Clearance Bracket enables this 3 point laser level to easily fit over steel stud track or create clearance for marking the floor. The amplified rare earth magnets provide a strong hold onto metal surfaces, while the integrated screw and nail hang holes allow easy and efficient setup in any environment. REDLITHIUM USB Batteries can be charged inside the laser via a Micro USB or swapped out with additional REDLITHIUM USB Batteries for virtually no downtime. The Milwaukee USB Rechargeable Green 3 Point Laser is covered by a two-year warranty.
