3.7V 360⁰ Green-Beam Three-Plane Leveling and Alignment Laser with Li-Ion Battery

The Bosch GLL300-42GL-RT 3.7V Green-Beam 360° Three-Plane Self-Leveling Laser is a reconditioned professional layout laser designed for leveling, alignment, and installation work in construction, framing, electrical, plumbing, HVAC, cabinetry, and finish trades. It projects one horizontal and two vertical 360° green laser planes for comprehensive jobsite layout from a single setup point.

Best Used For

  • Framing & Drywall: Establish level and vertical reference lines for walls, ceilings, partitions, and framing layouts.
  • Electrical, Plumbing & HVAC: Align conduit, piping, fixtures, equipment, and installation points across rooms and jobsite elevations.
  • Cabinetry & Finish Work: Create accurate horizontal and vertical reference planes for cabinets, millwork, trim, tile, and other finish installations.

Key Performance & Safety Features

  • Three 360° Green Planes: Projects one horizontal and two vertical laser planes to provide comprehensive leveling and alignment coverage from a single setup.
  • 100-Ft Working Range: Provides a working range of up to 100 ft without a receiver while maintaining a leveling accuracy of 1/8 inch at 30 ft under typical conditions.
  • Extended 260-Ft Range: Receiver-compatible operation can extend the horizontal line range to 260 ft when using a compatible receiver, sold separately.
  • Smart Pendulum System: Automatically self-levels within ±4°, indicates an out-of-level condition, and locks when switched off for transport.
  • IP65 Jobsite Protection: Dust-tight and water-resistant construction helps protect the laser in demanding jobsite environments.
  • Flexible Power: Uses the included rechargeable 3.7V 3.0 Ah lithium-ion battery or four AA batteries with the included adapter. USB-C charging also allows the laser to be powered while charging.

Commercial Layout & Optical Alignment Note:

Factory-reconditioned to meet original Bosch optical and leveling tolerances. High-visibility green laser diodes project three complete 360-degree planes, allowing trades to align whole-room acoustic ceilings, metal stud track layouts, plumbing pipe runs, and tile squaring from a single setup. The 3.7V rechargeable Lithium-Ion system charges via modern USB-C while the smart pendulum locks to safeguard diode calibration on bumpy jobsite rides.
