BOSCH GLL50-20G 50 Ft Green-Beam Self-Leveling Cross-Line Laser with Magnetic Mount

Bright, easy-to-see alignment for faster projects

The BOSCH GLL50-20G is a self-leveling cross-line laser that projects two level and plumb green beams across a workspace. The green beams are up to four times brighter than standard red lines, helping you see your reference marks even in brighter rooms or outdoors. With a generous 65-foot range and up to 1/4 inch accuracy at 30 feet, you can achieve quick, reliable alignment for tasks like installing shelves, hanging panels, or laying out tile lines.

In practical terms, this tool is designed to improve workflow without making you guess. The lines stay visible as you move around the room, and the Smart Pendulum System ensures the device self-levels. If the unit is out of level, a blinking indicator flags the issue, so you can adjust before locking and transporting the laser. Tilt the laser to project lines at an angle, expanding how you mark reference points across a space.

Power, durability, and professional build

Power flexibility is built in: operate with the included AA batteries or opt for the Bosch 3.7V Lithium-Ion 1.0 Ah battery (sold separately). The lithium option can run while charging, reducing downtime on longer jobs. The device carries an IP55 rating, resisting dust and water exposure on typical job sites. A full rubber overmold protects key impact points to help withstand daily wear.

Versatile mounting options add to the convenience: an integrated magnetic mount enables quick placement on metal surfaces, while a 1/4-inch thread accepts tripods for precise positioning. When tilted, you can use the lines at an angle to match sloped surfaces or stair layouts.
