The Bosch® GLL 30 self-leveling cross-line laser projects two lines, making a cross-line projection, for a wide array of level and align uses. This versatility makes it more valuable than a typical line laser. With top-notch accuracy and one-switch operation, the user's leveling and alignment tasks are done quickly and correctly. The laser lines are visible up to 30-foot. The smart pendulum system self-levels and indicates out-of-level condition to help ensure an accurate layout and it locks the lines at any angle. The pendulum system locks when switched off, to assure secure tool transport. The included MM 2 Flexible Mounting Device provides microfine height adjustment and it allows the laser to be clamped on virtually any surface from 1/2 to 2-1/4-inch thick, for level lines at any height.
