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. This green laser level features amplified rare earth magnets, providing a strong hold onto metal surfaces. The integrated screw and nail hang holes allow easy and efficient setup in any environment. You can charge REDLITHIUM™ USB Batteries inside the laser via a Micro USB or swap it out with additional REDLITHIUM™ USB Batteries for virtually no downtime.
