Making a Cut/Fill Lath
Once you have the stringline setup, fine-tune the height of the stringline above the grade. To do this, make a
cut/ fill lath using a lath and a Topcon cut/ fill decal.
1. Assemble the required number of laths for the job.
2. Measure from the bottom of the lath to the desired height above grade, and make a mark at that point.
Place the cut/ fill decal on the lath with “0” at the marked point (Figure 160).

3. Set the cut/ fill lath on the hub and read the cut or fill from the grade stake next to the hub. Adjust the clip
up or down until the stringline crosses the cut/ fill lath at that point (Figure 161).

The stringline is now set to 2 feet above finished grade.
The ST-3 is capable of indicating the center of the sensor to the stringline. Accurate placement of the
stringline helps to operate the screed shifting in/ out by using the ST-3 feature.
