Product Highlights

The Bosch GLL50-40G Green-Beam Self-Leveling 360° Cross-Line Laser uses green-beam technology, which emits green lines up to 4X brighter than standard red beams. This gives the laser a working range of up to 100 Ft. in diameter. The laser produces vertical line, 360° horizontal plane and cross-line modes, for a broad array of alignment and leveling applications. It provides 360° coverage to level with one setup point for an entire room. The tool has full rubber overmold housing, designed to be similar to a roll cage, so major impact points are reinforced with rubber. It has an IP64 rating and features deeply recessed windows help protect the laser glass. The one-button onboard user interface allows easy selection among the layout modes. The two-position recessed switch provides additional protection of the switch mechanism. The Bosch Smart Pendulum System self-levels and indicates out-of-level condition, and it locks the pendulum for secure transport. The included LB10 L-Bracket and DK10 ceiling clip offer quick setup and extra-strong magnets.
