Plumb Marks
The Product sends plumb marks up and down.
New Plumb Marks
To identify new plumb marks on a ceiling or roof:
1. Place a cross mark on the point to be transposed.
2. Center the down laser over the cross mark. See Figure 4.
3. Place a mark at the point where the up laser intersects the target area.
To identify new plumb marks on a oor, repeat the steps above but interchange the down and up lasers.
Note
Use the oor stand with the Product to increase the sight angle of the vertical down laser.
