LaserLine GR1000T Direct Reading Lenker Rod, 10 foot - Feet, Tenths, Hundreths

The LaserLine GR1000T is a professional-grade 10-foot aluminum Lenker-style direct reading rod scaled in feet, tenths, and hundredths — the standard unit system for civil grading, site development, and land surveying work across North America. By eliminating the mental arithmetic required with conventional rods, the GR1000T lets your crew lock in a benchmark elevation once and read actual ground elevations directly off the face of the rod for the entire shift. Less math on the job means fewer errors, faster layout, and more confidence at every shot.

Product Overview

The GR1000T is built around the proven Lenker moveable-tape design: a sliding aluminum face graduated in feet, tenths, and hundredths that you set to a known benchmark elevation at the start of the day. From that point forward, every rod reading your instrument operator calls out is the true elevation of that point on the ground — no subtraction, no addition, no calculator. The rod also incorporates a cut/fill scale on the reverse face, giving the rod person an immediate visual reference to how much material needs to move at any given stake without returning to a grade sheet. Constructed from lightweight, extruded aluminum sections with durable graduated markings, the GR1000T is built for daily field use on commercial grading sites, road construction corridors, utility trenching, and drainage work.

Job Applications

Site Grading & Mass Earthwork: On large commercial grading jobs where elevations are called out in feet and hundredths, the GR1000T keeps the grade checker moving fast. Set the rod to your benchmark, call elevations at every stake, and mark cut or fill without ever opening a grade sheet.

Road Construction & Subgrade Prep: DOT and municipal road projects demand hundredths-of-a-foot accuracy on subgrade and base course. The GR1000T's fine graduation and direct reading format match the tolerance standards inspectors verify in the field.

Drainage & Utility Trenching: Pipe grade and invert elevations in civil work are dimensioned in feet and tenths. The GR1000T lets the crew confirm pipe slope and invert elevation at every joint without pulling out a plan set for every calculation.

Benchmark Transfer & Elevation Control: Survey crews establishing temporary benchmarks across a large site can use the GR1000T with an automatic or digital level to efficiently transfer and verify control elevations throughout the workday.

Frequently Asked Questions

What is the difference between a Lenker rod and a standard grade rod?

A standard grade rod requires the instrument operator or rod person to subtract the rod reading from a known benchmark elevation to determine the elevation at each new point. A Lenker-style rod like the GR1000T has a moveable graduated face that you physically set to a known benchmark elevation. After that single setup step, every rod reading equals the true ground elevation at that point — no subtraction required. This dramatically speeds up grading and layout work.

Is the GR1000T compatible with my rotating laser level?

Yes. The GR1000T works with any rotating laser level when paired with a compatible laser detector and rod clamp. It is also fully compatible with optical automatic levels and total stations used in direct rod reading mode. The rod does not require any brand-specific laser receiver — use the detector you already own.

What does the cut/fill scale on the reverse face do?

The cut/fill scale on the back of the GR1000T allows the rod person to read how much material needs to be added (fill) or removed (cut) at each stake location, relative to the design grade. Instead of calculating the difference between current elevation and finish grade, the rod person simply reads the scale — a valuable time-saver during rough grading operations.

Can this rod be used for metric or decimal-foot conversions?

No. The GR1000T is graduated exclusively in feet, tenths, and hundredths of a foot — it is not convertible to metric. If your project plans are dimensioned in meters and millimeters, you will need a metric-graduated direct reading rod. For projects using the U.S. customary foot-tenth-hundredth system standard in civil engineering and land surveying, the GR1000T is the correct choice.
