The Nedo 345886 is a professional-grade 16-foot fiberglass measuring rod built for contractors who need accurate, repeatable readings on demanding job sites. With clear inch graduations and a rigid fiberglass core that resists warping, swelling, and UV degradation, this rod delivers consistent performance whether you're shooting grades on a foundation pour, checking excavation depth, or verifying finished floor elevations. At 16 feet of extended reach, you eliminate the stacked-section error that plagues telescoping rods on deep cuts and tall formwork.
Product Overview and Jobsite Applications
Nedo has built precision measuring tools for professional trades since 1919, and the 345886 reflects that legacy. This rod is engineered for surveyors, civil crews, and general contractors who run level and total station setups daily. The fiberglass construction keeps the rod dimensionally stable across temperature swings — no shrinking in dry heat, no swelling after a rain delay. The graduated face is high-contrast and readable at distance, reducing the chance of misread shots that cost you a re-pour or a re-grade.
Key Specifications
- Model: Nedo 345886
- Extended Length: 16 feet
- Graduation Type: Inch graduations
- Material: Fiberglass
- Application: Elevation measurement, grade verification, excavation depth
- Graduation Face: High-contrast markings for long-range readability
- Compatibility: Standard optical levels, laser levels, and total stations
Key Features
- Warp-Resistant Fiberglass Core: Maintains straightness across heat, cold, and wet conditions where wood rods fail
- Full 16-Foot Reach: Single-piece extended length eliminates stacked-section alignment error on deep excavations and tall pours
- High-Contrast Inch Graduations: Clearly marked face reads cleanly through optical levels and laser receivers at working distances
- Durable Construction: Built to withstand daily job site handling, transport in rod boxes, and exposure to UV and moisture
- Lightweight Design: Easy for one person to hold steady during shots without fatigue on long setups
- Standard Compatibility: Works with automatic levels, tilting levels, and laser level setups used by most construction crews
Job Site Applications
Foundation and Footing Layout: Shoot elevations on footing forms and verify bearing surface depths against engineered grades before concrete placement. A stable, non-warping rod means your benchmark shots match your check shots.
Excavation and Utility Trenching: At 16 feet, this rod reaches the bottom of deep utility cuts and storm sewer excavations without switching to a stacked rod setup. Depth checks are faster and more accurate with a single continuous scale.
Finish Grade and Drainage Verification: Walk grade stakes and verify positive drainage slopes on flatwork, parking lots, and retention areas. High-contrast graduations give your instrument operator clean readings across the site.
Vertical Formwork and Slab Elevation: Check wall form heights and slab screed elevations during placement. Fiberglass doesn't pick up the moisture of fresh concrete the way wood does, keeping your rod straight for the duration of the pour.

Frequently Asked Questions
- Is the Nedo 345886 a one-piece rod or does it extend in sections?
- The Nedo 345886 is designed to extend to 16 feet. Check product documentation or contact Express Tools to confirm whether it is a single-piece or collapsing multi-section rod, as section count affects portability and setup error accumulation.
- What type of level instrument is this rod compatible with?
- This rod works with standard automatic optical levels, tilting levels, and laser level setups that use a rod target or receiver. The inch graduation scale is readable with any optical level used in standard construction layout.
- Why choose fiberglass over a wood grade rod?
- Fiberglass resists moisture absorption, UV degradation, and temperature-related warping. Wood rods swell in wet conditions and shrink in dry heat, causing the graduation scale to shift and introducing cumulative error over a workday. Fiberglass rods maintain dimensional stability and stay straight under daily job site use.
- Can this rod be used with a laser level instead of an optical level?
- Yes. When paired with a compatible laser receiver or detector, this rod can be used with rotating laser levels for grade checking and elevation layout. Ensure your laser receiver clamp is compatible with the rod's diameter before field use.
