Johnson Level Tool 40-6646 3-point Laser Level 100 Ft

Product Description

The JOHNSON LEVEL TOOL 40-6646 is a self-leveling 3-point laser level designed for interior layout work including plumb and level alignment tasks in wall framing, drywall track installation, and structural layout. It projects two plumb dots and one level dot, giving installers a quick three-point reference without manual adjustment. The unit features a locking compensator that protects the pendulum mechanism during transport and storage. A visual out-of-level indicator alerts the user when the tool is outside its self-leveling range. The 40-6646 is suited for trade professionals working in residential and light commercial construction environments.

This laser level is built for use in framing, drywall, and general construction layout applications. Its tall profile provides clearance over wood or metal drywall track, making it practical for plumb-dot transfer through track openings without repositioning. The 100-foot range makes it useful for large open bays, warehouse interiors, and multi-room residential layouts. The 1/4 inch-20 tripod thread is compatible with most standard tripods, giving installers flexible mounting options across jobsite conditions. Two AA alkaline batteries are included. Dust-resistant construction supports use in active jobsite environments.

Installation Notes

Setup and operation is typically performed by carpenters, drywall installers, or general contractors. Mount the unit on a stable tripod or flat surface before powering on, and allow the self-leveling compensator to settle before taking reference shots. Keep the locking compensator engaged during any transport or repositioning to prevent damage to the pendulum. Do not use in environments outside the tool's self-leveling range without confirming the visual level indicator shows a valid reading.
