Bosch GLL50-20 50 ft Self-Leveling Cross-Line Laser with Magnetic Mount

Bosch GLL50-20: Compact, precise cross-line laser for quick, reliable layouts

The Bosch GLL50-20 delivers a bright cross-line projection with a 50-foot range, making it easier to establish horizontal and vertical reference lines across rooms, cabinets, and renovations. With 5/16 inch accuracy at 30 feet, you get clean, level lines that help you verify alignment without guesswork. The Smart Pendulum System keeps the laser self-leveling, while a blinking indicator alerts you to out-of-level conditions. When you’re finished, the device locks for secure transport, giving you peace of mind between jobs.

Power and durability are built into its design. The tool runs on two AA batteries (included) or can be paired with Bosch’s 3.7V Li-Ion 1.0 Ah battery (sold separately) so you can work while charging and reduce downtime. The full rubber overmold housing protects major impact points, functioning like a roll cage on a busy jobsite. An IP55 rating protects against dust and water, so you can rely on stable performance in a range of environments. The compact, ergonomic form makes it easy to carry and place, even in tighter spaces.
