BOSCH GLL50-20 50 Ft Self-Leveling Cross-Line Laser with Integrated Magnetic Mount

The BOSCH GLL50-20 50 Ft Self-Leveling Cross-Line Laser with Integrated Magnetic Mount is one of our picks for the laser level lineup. Everything below comes straight from the manufacturer's published listing - specs, capacities, and dimensions are theirs, not ours.

A self-leveling laser replaces the two-person string line: cross-line models throw plumb and level for interior layout, 360-degree models wrap a room in one setup, and green beams stay visible farther than red in bright conditions. Laser class varies by model — most cross-line tools are Class 2, some are Class 3R, and the class is printed on the tool. Check the marking on the unit you receive; whatever the class, never stare into the beam or point it at others, and check each listing's stated accuracy and range before buying for layout-critical work.

Key details, quoted from the manufacturer's published listing:

• POWER FLEXIBILITY: The laser works with two AA batteries (included) or Bosch's 3.7V Lithium-Ion 1.0 Ah battery (sold separately), for less downtime on the job.
• DURABLE: The laser is IP55 rated to withstand tough jobsite conditions such as rain or dust.
• ACCURACY: The laser has bright, thin lines that level within 5/16 inch accuract at 30 feet.
• SELF-LEVELING- The smart pendulum system self levels and indicates out-of-level condition by blinking and locks when switched off for secure transport.
• EASY-TO-USE: The laser is egonomic, compact and lightweight for easy use and storage.
• CLASS II LASER: 630 - 650 nm; <5 mW

The buying criteria for this category are laid out in measuring and layout tools and hand tools.
