Professional Self-Leveling Cross-Line Laser Level System with Multi-Axis Clamp Mount

The Bosch GLL30 is an industrial-grade self-leveling cross-line laser level engineered to project highly visible horizontal and vertical reference lines simultaneously for precise interior construction sizing. Driven by a Class II 635 nm laser diode rating, this compact layout instrument delivers an accuracy threshold of ±5/16-inch at 30 feet across an automatic self-leveling pendulum arc of up to 4 degrees. Outfitted with the Bosch-exclusive Smart Pendulum System that locks securely when powered down to safeguard internal calibrations during transport, this 1/2-pound layout tool includes an MM 2 flexible mounting device with a 360-degree rotating neck to clamp onto jobsite studs, pipes, or tables ranging up to 2-1/4 inches thick.

Best Used For:

  • Commercial Cabinetry Alignment: Levelling long-run cabinet bases and plumbing wall-mounted storage units accurately across interior layouts.
  • Wall Tile and Backsplash Grid Layouts: Projecting crisp perpendicular cross-line references to map out ceramic or stone tile layout lines over vertical surfaces.
  • Residential Wood and Metal Framing: Squaring vertical track positions and plumbing wall stud locations across residential basement additions.

Key Performance & Safety Features

  • Simultaneous Cross-Line Mode: Projects two intersecting bright red lines that are precisely level and plumb for comprehensive alignment applications.
  • Smart Pendulum Auto-Leveling: Internal gravity pendulum self-corrects orientation angles within a 4-degree arc and displays a warning signal when pushed out of alignment.
  • MM 2 Flexible Mounting Device: Included multi-surface mounting clamp features a 360-degree rotating neck to secure the chassis onto studs or pipes from 1/2 inch to 2-1/4 inches thick.
  • Secure Pendulum Transport Lock: Internal mechanical pendulum clamps firmly when powered down to protect the sensitive calibration setup from field vibration shock.
  • Universal Spindle Compatible Threading: Integrated with a standard 1/4-inch-20 brass thread path to mount directly onto standard survey tripods or the included flexible clamp bracket.

What's Included

  • (1) GLL30 Self-Leveling Cross-Line Laser Level
  • (1) MM 2 Flexible Mounting Device

Pro-Tip: When working inside brightly lit rooms or across spaces with ambient sunlight filtration, place a dedicated target plate or raw structural stock at your 30-foot layout boundary. Intersecting the red cross-lines directly against a targeted edge surface increases visual clarity and simplifies level verification before securing hardware elements.
