The MILWAUKEE® USB Rechargeable Green Cross Line Laser is powered by REDLITHIUM™ USB, delivering all day runtime and uncompromised visibility. The high-intensity laser beams allow visibility of green lines up to 100' for fast and accurate leveling and alignment. The integrated magnetic bracket features micro control that provides a faster set-up and point to point alignment at long distances. The amplified rare earth magnets provide a stong hold onto metal surfaces while the integrated screw and nail hang holes make setup easy and efficient in any environment. The REDLITHIUM™ USB Battery can be charged inside the laser via Micro USB or swap it out with additional REDLITHIUM™ USB Batteries for virtually no downtime. The Milwaukee USB Rechargeable Green Cross Line Laser is covered by a two-year warranty.
