MAXIMUM VERSATILITYThe Bosch GLL50-40G green-beam self-leveling 360° uses green-beam technology and provides 360° coverage to level with one setup point for an entire room. It produces a vertical line, 360° horizontal plane, and cross-line modes - for a broad array of alignment and leveling applications. |
SMART LEVELINGThe GLL50-40G has uses a Smart Pendulum System and self-levels and indicates out-of-level condition so the user can have confidence in the accuracy of the measurements. The system locks the pendulum when the tool is switched off, to help preserve the tool’s precision over time and to protect the laser during transport. |
VERSATILE ATTACHMENTS FOR A WIDE VARIETY OF APPLICATIONSThe GLL50-40G includes the LB10 L-Bracket and DK10 ceiling clip which offer quick setup and extra-strong magnets, for a variety of leveling and alignment applications, such as drop ceiling installation. |
