The MILWAUKEE® USB Rechargeable Green Cross Line Laser is powered by REDLITHIUM USB, delivering all-day runtime and uncompromised visibility. High-intensity laser beams allow you to see green lines up to 100 feet for fast and accurate leveling and alignment. The integrated magnetic bracket features micro-control that provides faster set-up and point-to-point alignment over long distances. Amplified rare earth magnets provide a strong hold to metal surfaces, while integrated screw and nail hanging holes make set-up easy and efficient in any environment. The REDLITHIUM USB battery can be recharged inside the laser via Micro USB or swapped out with other REDLITHIUM USB batteries for virtually no downtime. The Milwaukee USB Rechargeable Green Cross Line Laser is covered by a two-year warranty.
