Achieve accurate levelling and alignment in demanding working environments with the Bosch PRO GLL 18V-120-33 CG Cordless Line Laser. Designed for construction professionals, installers and tradespeople, this versatile measuring tool combines three green 360° laser lines, flexible power options and robust construction to deliver dependable performance on challenging jobsites.
The GLL 18V-120-33 CG projects three 360° laser lines, providing comprehensive horizontal and vertical reference lines for a wide range of levelling and alignment applications. Its green laser technology improves line visibility, making it particularly useful when installing suspended ceilings, constructing partition walls, positioning door frames and completing other precision installation tasks.
With a working range of 35m and an accuracy of ±0.3mm/m, the laser provides reliable reference lines for professional construction work. When used with the compatible Bosch LR 7 laser receiver, its working range extends to 120m in radius, supporting applications across larger working areas.
One of the tool's standout features is its triple power source concept. Users can operate the laser using a compatible Bosch 18V lithium-ion battery, a compatible 12V lithium-ion battery or four 1.5V LR14 alkaline C-cell batteries. This flexibility helps minimise downtime by providing alternative power options when a particular battery system is unavailable.
Built for demanding environments, the GLL 18V-120-33 CG features a rubber-reinforced housing and reinforced laser windows. Its IP65 protection rating provides resistance to dust ingress and water jets, making it suitable for challenging construction site conditions when used according to the manufacturer's instructions.
The integrated mounting system features strong magnets for secure positioning on suitable magnetic surfaces. A precise pivot fine-adjustment mechanism allows users to adjust the vertical laser line without losing the original reference point, simplifying accurate alignment during installation work.
For additional convenience, the backlit corner keypad allows individual selection of the laser lines. This helps users activate the required projections while maintaining control over the measuring setup.
The GLL 18V-120-33 CG also supports the Bosch Levelling Remote app, allowing compatible mobile devices to control laser functions remotely. This hands-free functionality is particularly useful when working away from the laser or making adjustments that could otherwise disturb its position.
Its self-levelling mechanism operates within a range of ±4° and completes levelling in approximately three seconds under suitable conditions. This helps users establish accurate reference lines quickly and reduces the time required for manual adjustments.
With 1/4" (6.35mm) and 5/8" (15.88mm) tripod threads, the laser supports a range of compatible mounting accessories. The supplied ceiling clip and L-BOXX carrying case further improve its practicality for professional installation and transport.
Whether installing drywall partitions, aligning studs, positioning windows and doors, setting out suspended ceilings or installing pipework, the Bosch PRO GLL 18V-120-33 CG provides the precision, flexibility and durability required for professional levelling applications.
The Bosch GLL 18V-120-33 CG projects three green 360° laser lines, providing comprehensive reference lines for horizontal and vertical alignment.
This configuration allows users to establish accurate reference planes around the working area, making it useful for tasks that require consistent positioning across walls, floors and ceilings.
The green laser lines provide improved visibility in many working environments, helping users identify reference positions during construction and installation work.
The GLL 18V-120-33 CG features a flexible power system designed to reduce interruptions during professional use.
The laser supports three power configurations:
This versatile design allows users to switch between compatible power sources according to availability and working requirements.
The laser provides a standard working range of 35m, making it suitable for a variety of indoor construction and installation applications.
When paired with a compatible Bosch LR 7 laser receiver, the working range extends to 120m in radius.
This expanded range supports levelling and alignment across larger working areas where direct laser line visibility may be limited.
The GLL 18V-120-33 CG delivers an accuracy of ±0.3mm/m, supporting precise positioning and alignment.
Its automatic self-levelling system operates within a range of ±4° and completes levelling in approximately three seconds under suitable conditions.
This helps users establish reliable reference lines quickly without spending unnecessary time on manual adjustments.
The Bosch GLL 18V-120-33 CG is designed for demanding professional environments.
Its rubber-reinforced housing and reinforced laser windows provide additional protection against everyday jobsite impacts.
The IP65 rating indicates dust-tight protection and resistance to water jets under the applicable test conditions.
These features support reliable use in challenging environments, although the tool should not be submerged or subjected to conditions outside the manufacturer's recommendations.
The laser features an integrated mounting system with strong magnets for secure positioning on suitable magnetic surfaces.
Its pivot fine-adjustment mechanism allows users to alter the position of the vertical laser line without losing the established reference point.
This is particularly useful when aligning wall framing, door openings, ceiling components and other construction elements requiring precise positioning.
The GLL 18V-120-33 CG supports remote operation through the Bosch Levelling Remote app on compatible mobile devices.
This allows users to control supported laser functions without physically touching the instrument.
Remote control can help prevent accidental movement of the laser during setup and makes adjustments more convenient when working at a distance.
The integrated backlit corner keypad provides convenient access to the laser's operating controls.
Users can select individual laser lines according to the application, allowing the required reference lines to be displayed without activating unnecessary projections.
The illuminated controls also improve usability in poorly lit working environments.
Please Note: This product is supplied as a bare tool. Lithium-ion batteries and chargers are not included. The supplied scope of delivery also does not list alkaline batteries or a laser receiver. These must be purchased separately if required.
Please Note: The extended working range of 120m requires a compatible Bosch LR 7 laser receiver. Actual laser visibility and working range depend on ambient lighting and operating conditions.
Please Note: The stated operating times depend on the power source, battery capacity, selected laser lines and operating conditions. The alkaline battery runtime is specified for energy-saving mode with all three laser lines active.
