MN-4RG 4×360° Laser Level with Digital Angle Display

For professional tool brands, a high-performance laser level needs to provide more than full-room laser coverage. Precise positioning, easy adjustment, stable support, and flexible power options are increasingly important for professional users.

The MN-4RG 4×360° Self-Leveling Cross Line Laser combines four 360° laser planes with a digital angle sensor, precision fine adjustment, a rotatable metal base, a metal laser window, four working modes, and a DeWALT 12V-compatible power interface. It provides a professional platform for construction, installation, renovation, and layout applications.

4×360° Laser Coverage for Full-Room Layout

The MN-4RG provides 4×360° laser coverage, creating continuous horizontal and vertical reference planes around the working area.

This full-room layout capability helps reduce the need to repeatedly reposition the laser during demanding installation work.

It can support applications such as:

• Suspended ceiling installation

• Floor and tile layout

• Wall and partition alignment

• Cabinet and interior installation

• Door and window positioning

• Construction and renovation layout

For professional contractors, broader laser coverage makes it easier to maintain consistent reference lines across multiple surfaces.

Digital Angle Display Shows Laser Line Tilt

One of the key features of MN-4RG is its high-precision angle sensor and LCD display.

Instead of simply showing the physical tilt of the laser device, the system displays the tilt angle of the projected laser line on the LCD screen.

This gives users more direct information when working on angled layouts and helps reduce guesswork during precision positioning.

For brands targeting professional users, this feature provides a clear product differentiator beyond standard self-leveling laser functionality.

Fine Adjustment Knob for Precise Laser Positioning

Small positioning errors can require repeated repositioning of the entire laser tool.

The MN-4RG uses a precision fine-tuning knob that allows users to correct minor laser deviations without moving the complete unit.

The system also supports fine adjustment and base rotation, giving users greater control when aligning the projected laser lines.

This can be particularly useful for installation work where the laser reference needs to be positioned accurately without disturbing the original setup.

Rotatable Metal Base and Laser Window for Stable Setup

Stable positioning is critical when working with precise laser references.

The MN-4RG features a heavy metal base designed to provide stable placement during operation.

A rotatable metal laser window enables full-angle laser emission while adding protection to the laser optics.

Together, the metal base and metal window create a more robust mechanical design for professional jobsite applications and help support long-term product durability.

Four Working Modes for Leveling, Angled Layout and Outdoor Use

The MN-4RG provides four operating modes for different working requirements.

Auto-Leveling Mode
Automatically levels the laser within a 4° ±1° self-leveling range.

Manual Mode
Allows users to position the laser lines at a free angle when an inclined reference is required.

Pulse Mode
Designed for use with a compatible laser receiver, extending the tool's application potential in brighter or longer-distance working environments.

Brightness-Adjustable Power-Saving Mode
Allows users to adjust laser brightness while reducing unnecessary power consumption when maximum output is not required.

This combination gives brands a versatile platform for both standard leveling and specialized layout applications.

DeWALT 12V Battery Compatibility for Flexible Power

The MN-4RG features a universal DeWALT 12V-compatible power interface.

This design allows the laser level to integrate with a widely recognized professional cordless-tool battery platform, providing a practical power solution for users who already operate compatible 12V tools.

For tool brands, battery-platform compatibility can also be an important product positioning feature when developing professional laser tools for established cordless-tool ecosystems.

IP54 Protection for Professional Jobsite Conditions

Laser levels used in construction and renovation environments may be exposed to dust, water splashes, and accidental handling.

The MN-4RG uses an IP54-rated design to provide protection against dust ingress and water splashes.

Combined with its heavy metal base and rotatable metal laser window, the design is intended to support reliable operation in professional working environments.
