Description

Achieve Professional Precision and Durability with the Bosch GLL50-20

The Bosch GLL50-20 Self-Leveling Cross-Line Laser is the perfect solution for professionals seeking accuracy and versatility in a compact layout tool. Featuring a reliable 50 Ft. range, this laser projects highly visible horizontal and vertical red lines, allowing for precise leveling with 5/16 In. accuracy at 30 Ft.. Whether you are installing cabinets, framing a room, or aligning tile, the Smart Pendulum System ensures the tool self-levels and provides an immediate warning if an out-of-level condition occurs. For specialized tasks, simply tilt the laser to project lines at any angle, while the manual lock secures the pendulum for safe transport between jobsites.

Built to survive the toughest conditions, the GLL50-20 features a full rubber overmold housing that acts like a roll cage to protect against impacts. With an IP 55 rating for dust and water resistance, this tool is as dependable as it is durable. One of its most innovative features is dual-power flexibility: use the included AA batteries to get started immediately, or upgrade to the Bosch 3.7V Lithium-Ion battery (sold separately) to enable continuous operation even while charging. The integrated magnetic mount and 1/4 In.-20 tripod threading offer endless positioning options, ensuring this laser fits perfectly into your existing workflow.

Key Features

  • Dual Power Flexibility: Operates on two AA batteries (included) or an optional 3.7V Lithium-Ion 1.0 Ah battery (sold separately).

Pro-Tip: When using the magnetic mount on metal studs, place a piece of painter's tape on the stud first. This prevents the strong magnets from scratching the finished surface or the tool, and makes it easier to slide the laser for fine-tuned height adjustments.
