This tool projects rotating, dithering and stationary laser points and is intended for accurate
transfer and alignment of plumb, level, graded and 90-degree points and lines.
•
Plumbing (Making vertical) —
Use the tool in the vertical orientation for indoor and outdoor
plumb applications, such as plumbing up framing, aligning cabinetry, etc.
•
Leveling —
Use the tool in the horizontal orientation for indoor and outdoor level
applications, such as leveling cabinetry, setting concrete forms, leveling electrical
outlets, etc.
•
Grading —
Use the tool at a sloped angle for indoor and outdoor level applications, such
as grading driveways or swimming pools.
•
Squaring—
The laser beam emitting from the top of the tool is perpendicular to the rotating
beam, which provides the ability to use the tool for 90 degree layout functions.
