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

The Bosch GLL30-RT is an industrial-grade factory-reconditioned self-leveling cross-line laser level engineered to project highly visible horizontal and vertical reference lines simultaneously for precise interior construction sizing and layout. Driven by a Class II 635 nm laser diode rating, this compact instrument delivers a reliable 30-foot working range and a technical 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 self-corrects and locks securely when powered down to protect 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, channels, or trim surfaces up to 2-1/4 inches thick.

Note: This is a manufacturer-reconditioned tool, certified to look and perform like new.

Best Used For:

  • Commercial Cabinetry Alignment: Leveling long-run cabinet bases and plumbing wall-mounted storage modules accurately across interior structural layouts.
  • Wall Tile and Grid Layouts: Projecting crisp perpendicular cross-line references to map out ceramic tile or stone layout lines over vertical surfaces.
  • Residential Structural Finish Framing: Squaring vertical track positions, installing acoustic ceiling grids, and plumbing partition wall stud locations rapidly.

Key Performance & Safety Features

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

What's Included

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

Pro-Tip: When capturing target lines in rooms with high ambient sunlight filtration, place a dedicated high-contrast target cards or a raw piece of framing stock at your 30-foot layout terminus. Intersecting the red cross-lines directly against a rigid edge surface increases visual clarity and simplifies level verification before securing structural components.
