The Bosch GLL 40-20G Self-Leveling Green Beam Cross-Line Laser is an excellent device for a wide range of level and align applications. A one-switch operation, coupled with its smart pendulum system, allows for a very quick setup. Its casing has a good quality composite plastic material.
Accurate and Bright Lines: The device projects highly visible Green laser lines, that are twice as bright as a red laser and precisely level at a distance of up to 40 feet. The projected laser lines have a high level of accuracy, having a tolerance of just ±5/16". Its versatility, accuracy and ease-of-use makes it much more valuable than any typical line laser.
Smart Pendulum System: The smart pendulum self-levels and indicates when the device is out-of-level. When the device is switched off, the pendulum gets locked in its place, this helps in ensuring a long tool life
Ergonomic Mounting System: The device is very easy to use and easy to store. The included MM 2 flexible mounting device can stably clamp to many different surfaces, of 1/2" to 2-1/4" thickness, and has a rotating 360° neck for quick setup which can be fine-tuned as well. The laser module features a 1/4"-20 tripod thread for use with either the MM 2 mount or a tripod.
