Seco 98010 SVR Series 25-Foot Fiberglass Grade Rod (10ths)
The Seco 98010 SVR is built for layout and grading crews who need reliable elevation readings over long sight distances without resetting multiple times. Constructed from durable fiberglass, this 25-foot rod handles the daily punishment of concrete pours, drainage verification, roadway grading, and site elevation control. Its 10ths (decimal foot) graduations deliver the precision that civil contractors, surveyors, and utility crews depend on from the first setup to the final as-built check.
Product Overview & Jobsite Applications
The SVR Series from Seco is engineered specifically for contractors and survey crews working in demanding field conditions. The rectangular-oval cross-section profile prevents rolling on uneven or sloped surfaces, and the glare-resistant graduated markings remain readable under bright sunlight or overcast conditions. Whether you are setting grades for a storm drainage system, checking subgrade elevations on a highway project, or managing a concrete foundation pour, the Seco 98010 delivers the reach and readability to keep work moving efficiently.

Key Features
- 25-Foot Reach: Covers long sight distances typical of roadway, drainage, and large site grading work — fewer setups, faster progress
- Tenths Graduations: Decimal foot markings integrate directly with civil engineering and grading calculations without conversion
- Glare-Resistant Scale: High-contrast, non-reflective markings remain legible in harsh sunlight and changing field conditions
- Anti-Roll Profile: The rectangular-oval cross section keeps the rod stable on sloped terrain, reducing read errors from rod movement
- Fiberglass Construction: Resists warping, moisture absorption, and jobsite impact better than wood rods while remaining lightweight for field transport
- SVR Graduation Pattern: Seco's proven direct-reading format compatible with optical auto levels, laser detectors, and total stations
Job Applications
Roadway & Highway Grading: Establish and verify subgrade, base, and finish surface elevations across long station intervals with a single rod position.
Storm Drainage & Utility Layout: Confirm pipe invert elevations, manhole rim grades, and slope percentages accurately on utility installation projects.
Concrete Foundation Pours: Monitor form elevations and verify finished slab grades during concrete placement where precision and speed matter most.
Site Development & Earthwork: Check cut and fill elevations across large grading sites where extended sight distances eliminate unnecessary instrument moves.

Frequently Asked Questions
- What does "10ths" graduation mean on a grade rod?
- Tenths graduations measure in decimal feet — each foot is divided into ten equal increments of 0.1 feet. This format eliminates the need to convert from inches and integrates directly with civil engineering grade sheets, elevation calculations, and machine control systems used on most commercial and infrastructure projects.
- Can the Seco 98010 be used with a laser level and detector?
- Yes. The SVR Series rod works with laser receivers and detectors mounted to the rod when setting grades with a rotating laser level. It is also compatible with optical auto levels and total stations for conventional differential leveling.
- How does the anti-roll profile improve field accuracy?
- The rectangular-oval cross section gives the rod a flat bearing surface so it does not drift or rotate when set on sloped ground or uneven terrain. Rod movement during a reading is a common source of elevation error — the SVR profile minimizes that risk without requiring the rodman to hold constant tension.
- Is the Seco 98010 suitable for wet or muddy jobsite conditions?
- Fiberglass resists moisture absorption and will not warp or swell the way wooden rods do when exposed to rain, mud, or standing water. The graduation markings are also sealed into the rod surface rather than printed on paper, so they remain legible through normal field exposure over the life of the tool.
