Bosch GLL55 Professional Self-Leveling Cross-Line Laser


The Bosch GLL 55 Professional Self-Leveling Cross-Line Laser projects vertical, horizontal and cross lines, independently or together. It features VisiMax technology, for outstanding line visibility in standard working conditions. The locking Smart Pendulum System provides accuracy, reliability and durability. The tool is easy to use and provides a variety of essential level and alignment applications. The unit is constructed to withstand harsh jobsite conditions. The set includes a magnetic L mount that attaches to steel studs, and it is equipped with free-standing mode functionality. The included hard carrying case provides for more secure laser transport.

VisiMax for outstanding visibility - The GLL 55 Cross-Line Laser features the Bosch-exclusive VisiMax technology, which delivers maximum beam brightness in most jobsite conditions. It provides highly visible lines while protecting the laser diodes from overheating. VisiMax constantly monitors the laser's temperature so the diodes are always driven to deliver the best line visibility while preserving the life of the tool.

Layout efficiency - This professional cross-line laser includes vertical, horizontal and cross-line modes, which can project two lines independently or together. The GLL 55 has a manual mode that allows the user to lock the cross-line, to use the tool at any angle. The laser's lines are highly visible up to 50 Ft. and offer accuracy of ±1/8 In. at 33 Ft. The tool provides a long vertical laser line that extends line visibility to a nearly 360-Degree vertical plane when placed next to a wall.
