Seco 92021 Measuring Rod 13-foot Fiberglass TENTHS - Seco

Seco 92021 Fiberglass Leveling Rod — Built for the Demands of the Field

The Seco 92021 is a professional-grade 13-foot fiberglass leveling rod engineered for surveyors and contractors who need reliable, accurate readings on every shot. Whether you're running a leveling loop across a construction site or establishing benchmarks on a civil project, this rod delivers the precision and durability that fieldwork demands. Graduated in tenths, it works seamlessly with optical levels, builder's levels, and laser transits for fast, error-free readings.

Overview & Jobsite Applications

Designed for day-in, day-out professional use, the Seco 92021 pairs a lightweight fiberglass build with bold, high-contrast graduations that are easy to read at distance. The three-section telescoping design lets crews cover full 13-foot elevations when needed, then collapse the rod to a compact 58.375 inches for quick moves between setups and hassle-free transport in a crew cab or job trailer. The rectangular cross-section with rounded back corners gives rodmen a secure, fatigue-reducing grip during long leveling runs.

Frequently Asked Questions

What is the collapsed length of the Seco 92021?

When fully collapsed, the Seco 92021 measures 58.375 inches, making it practical to transport in most trucks, vans, and job trailers without disassembly.

Is the Seco 92021 compatible with laser levels?

Yes. The rod's tenths graduations work with rotating laser levels and laser transits in addition to traditional optical levels and builder's levels. Use a laser detector for best results in bright outdoor conditions.

Why choose fiberglass over a wooden leveling rod?

Fiberglass rods like the Seco 92021 resist moisture absorption, warping, and shrinkage that can compromise the accuracy of wooden rods over time. Fiberglass also holds up better to the physical demands of daily fieldwork and does not require the same seasonal recalibration concerns associated with wood.

How many sections does the Seco 92021 have?

The Seco 92021 is a three-section rod. Each section locks securely in place so the rod stays at the extended length you need throughout your leveling run.
