The strong 360° horizontal line projects a laser reference line around the room with accuracy to quickly establish level. The Bosch GLL 2-20 range is 65 ft. diameter and accuracy is ± 3/16″ at 30 ft.
The Bosch Smart Pendulum System on the GLL 2-20 offers self-leveling, one-time setup along with an out-of-level warning indicator. Its pendulum lock protects the most sensitive component of the laser for easy and safe transport.
