Construction Grade Rod
DANGER: NEVER attempt to use a grade rod in a storm or
near overhanging electric wires. Death or serious personal injury
will occur.
Some laser kits include a grade rod. The D

in telescoping sections. A spring-loaded button actuates a lock to
hold the grade rod at various lengths.
The front of the grade rod has the measurement
scale starting at the bottom. Use this for measuring
from the ground up when grading or leveling
jobs.
The back of the grade rod is designed to measure
