Seco 92041 16-foot Fiberglass Rectangular Series (CR) — Tenths Graduations

Seco 92041 — 16-Foot Fiberglass Grade Rod for Contractors and Surveyors

The Seco 92041 is a professional-grade 16-foot fiberglass leveling rod engineered for surveyors, civil contractors, and site superintendents who demand fast, accurate elevation readings under real jobsite conditions. With feet/10ths graduations printed directly on durable fiberglass sections, this rod eliminates the mental math of fractional conversions and keeps your crew moving. Whether you're shooting grades for a foundation, setting drain inverts, or checking finished subgrade, the 92041 is built to deliver dependable results setup after setup.

Product Overview & Jobsite Applications

The Seco 92041 combines a rugged four-section telescoping design with a full 16-foot range, covering the vast majority of elevation shots encountered on residential and light commercial projects — all from a single instrument setup. The fiberglass construction resists warping, moisture absorption, and the UV exposure that degrades cheaper rods over time. Graduated in feet and tenths, the rod pairs seamlessly with digital levels, optical levels, and laser receivers to give rod persons accurate, readable data from any working distance. Its collapsed length makes transport and staging simple, and each section locks securely so readings don't shift mid-shot.

Key Specifications

• Model: Seco 92041
• Length (Extended): 16 feet
• Graduation System: Feet and 10ths (decimal feet)
• Number of Sections: 4 telescoping sections
• Material: Fiberglass construction
• Laser Receiver Ready: Yes — accepts standard laser detector brackets
• Application: Optical levels, digital levels, laser levels
• Graduation Style: E-face (standard face) graduation pattern

Key Features

• Feet/10ths decimal graduations eliminate fractional conversion on the rod and in the field notes
• Four-section telescoping design collapses for easy one-person transport and vehicle storage
• Fiberglass sections resist moisture, UV, and dimensional changes that affect wood and aluminum rods
• Laser receiver compatible — mount your detector directly to the rod for grade-setting with rotary lasers
• High-contrast graduation markings remain legible at instrument distances typical of construction sites
• Positive-locking section joints keep the rod at a stable, consistent length during shots
• Lightweight enough for extended use without fatigue during long layout sessions

Job Applications

Foundation & Footing Layout: Shoot elevation benchmarks and set batter board heights with decimal precision — feet/10ths readings transfer directly to your plan dimensions without conversion.

Site Grading & Earthwork: Check cut and fill elevations against design grade at each stake location. The 16-foot range handles most earthwork shots without moving the instrument.

Utility & Drain Installation: Set storm and sanitary invert elevations with a rotary laser and receiver mounted to the 92041 — no instrument operator required once grade is established.

Finished Floor & Slab Elevation Checks: Verify slab pours and floor elevations against survey control with an optical or digital level for quality control documentation.

Frequently Asked Questions

What does feet/10ths graduation mean on the Seco 92041?

Feet/10ths (also called decimal feet) means the rod is graduated in feet divided into ten equal parts rather than inches and fractions. One tenth of a foot equals 1.2 inches. This system is standard in engineering and construction surveying because elevation values read directly from the rod match the decimal units used on civil plans and grade sheets, eliminating the need for conversion calculations in the field.

Can I use the Seco 92041 with a rotary laser level?

Yes. The 92041 is laser receiver ready, meaning it accepts standard laser detector brackets that clamp to the rod body. Attach a compatible laser detector, set it to your design elevation, and the rod person can check and set grade independently without an instrument operator — a major efficiency advantage for drainage, subgrade, and concrete form work.

How many sections does the Seco 92041 have, and how short does it collapse?

The 92041 is a four-section telescoping rod. When fully collapsed, each section nests inside the next, reducing the overall length for transport and storage in a truck bed, van, or equipment room. The locking joints on each section hold their position firmly once extended so the rod length stays consistent throughout a setup.

Is fiberglass a good material for a grade rod?

Fiberglass is widely preferred for professional grade rods over wood and aluminum because it does not absorb moisture, is dimensionally stable across temperature changes, and resists UV degradation. It will not warp or swell the way wood rods can, and it does not conduct electricity, making it safer near overhead power lines or energized equipment. For a rod that will be used regularly on varied jobsite conditions, fiberglass is the professional standard choice.
