Item Brochure

LaserLine Mfg., Inc. is the world's largest manufacturer of direct reading (Lenker style)
grade rods. We are proud to offer the highest in quality, selection and service.
Laser Version Direct Reading/
True Elevation Rods
For use with a laser detector. There is a special
rail slide and Laserline detector bracket that
lets the laser detector travel the full working
length of the rod. This allows faster and easier
readings because it takes the awkwardness
out of having to loosen the detector, move
the detector, then tighten the detector for
each reading.
Optical Version Direct Reading/
True Elevation Rods
Are used with optical instruments and have
no special rail for the laser detector. All tape
faces have large scales and are easy to read at a
distance when using an optical instrument.
Laserline offers the largest selection of direct reading (Lenker style) grade rods available.
Refer to “Detecor Brackets Match Guide”
(last page) for your bracket selection.
Direct Reading/True Elevation Grade Rod
Direct Reading, or True Elevation (also known as Lenker style) is a Grade Rod with a moveable tape face
allowing you to set the actual benchmark elevation, or any elevation, above or below the bench into the
rod. The actual true elevation above sea level is read on these rods, thus eliminating errors caused by adding
or subtracting. Since no math is involved, grade shots are much faster than conventional style rods.
On most jobsites, the bench elevation is typically established by survey, and all elevations on that project are
above that or below primary bench elevation.
Read on rod as

HOW THEY WORK:
EXAMPLE:

are typically represented in
