The Bosch GLL 55 professional self-leveling cross-line laser features vertical, horizontal and cross-line modes and can project two lines independently or together, for a broad array of alignment and leveling applications. It includes the Bosch-exclusive VisiMax technology, which allows for outstanding line visibility in most working conditions. The Bosch Smart Pendulum System self-levels and indicates out-of-level condition so your marks are always straight and true.
