Johnson Dot Laser Levels

 

>> Dot Laser Applications    

The Dot Laser Level line is your best choice when you want to find a level point, or points at 90 degrees between a wall, the floor and the ceiling.

Electricians use this laser level for accurate placement of  lighting fixtures. Carpenters use this Laser Lever for layout of interior walls and beams.

Most of these dot laser levels are self leveling, so you get an accurate measurement instantly, even on uneven ground. Johnson Dot laser levels are easy to see because of the concentrated beam for all indoor construction applications.

Johnson dot laser levels are available in two-beam, three-beam, and five-beam dot laser level models to meet the needs of every construction application.

Common uses for a dot laser level are setting foundations and footings, alignment of concrete forms, and layout of interior walls, electrical wiring & outlets, plumbing pipes, cabinets, countertops and MUCH more.
