SitePro 11-SPR17-C 17-foot SPR Type Fiberglass Grade Rod - Measurement in INCHES

Built for the Jobsite — SitePro 17ft Fiberglass Grade Rod

The SitePro 11-SPR17-C is a contractor-grade 17-foot fiberglass leveling rod engineered for accurate, repeatable elevation readings across demanding jobsite conditions. Whether you're running grades on a commercial site, setting foundation benchmarks, or doing precision layout work, this rod delivers the reliability professionals depend on. The SPR-type feet and inches graduation pattern is clearly printed for fast, confident readings from both optical and digital levels at extended distances.

Product Overview & Jobsite Applications

Fiberglass construction makes this rod the smart choice over aluminum or wood alternatives. It won't warp in humidity, corrode in wet conditions, or conduct electricity near overhead hazards — critical advantages when work takes you across varied terrain and weather. The 17-foot extended reach gives you flexibility on sites with significant elevation changes, reducing the number of instrument setups needed and keeping your crew moving efficiently. The SPR graduation style aligns with standard optical level readout conventions, making this rod compatible with virtually any automatic, digital, or optical instrument in the field.

Key Specifications

Key Features

• Non-conductive fiberglass construction — safer near power lines and electrical hazards on active jobsites
• Moisture and warp resistant — maintains dimensional accuracy in rain, humidity, and field storage conditions
• SPR feet & inches graduations — clearly printed scale for fast, low-error rod readings at distance
• 17-foot extended reach — covers significant elevation changes with fewer instrument moves
• Lightweight design — reduces rodman fatigue during long measurement sessions
• High-contrast markings — enhanced visibility in bright sunlight and low-light conditions
• Durable construction — built to withstand daily transport, rough handling, and outdoor storage

Job Applications

Site Grading & Earthwork: Set and verify cut/fill grades across large areas using a single instrument setup. The 17-foot length handles rolling terrain without constant repositioning, keeping production on track.

Foundation & Concrete Layout: Establish precise elevation benchmarks for footings, slabs, and stem walls. Accurate rod readings mean fewer costly errors at the concrete stage where corrections are expensive.

Utility & Pipeline Work: Verify invert elevations and pipe slope during storm drain, sewer, and water main installation. The fiberglass material holds up in muddy trench conditions without compromising accuracy.

General Surveying & Construction Layout: Ideal for crews running differential leveling loops, checking existing elevations, or establishing control benchmarks across commercial and residential projects.

Frequently Asked Questions

What does the "SPR" designation mean on this grade rod?

SPR refers to the graduation style — in this case, feet and inches markings formatted for reading with standard optical and automatic levels. The SPR pattern uses a specific tick-mark layout that makes rod readings fast and unambiguous for the instrument operator, reducing miscommunication between the rodman and the level operator on busy sites.

Is this rod compatible with digital levels as well as optical levels?

The 11-SPR17-C is primarily designed for use with optical and automatic levels that read traditional feet-and-inches SPR graduations. For use with electronic digital levels, you would typically need a rod with a bar-code graduation pattern. Check your digital level's manual for rod compatibility before purchasing.

Why choose fiberglass over an aluminum grade rod?

Fiberglass offers three key advantages on working jobsites: it is non-conductive making it safer near electrical hazards, it does not corrode or oxidize in wet and muddy conditions, and it resists warping caused by moisture absorption — a common issue with wood rods. Aluminum rods are lightweight but can conduct electricity and may dent or bend under rough handling.

Can this rod be used for metric measurements?

No — the SitePro 11-SPR17-C is graduated in feet and inches in the SPR format. If your project requires metric readings (meters and millimeters), you will need a metric-graduated rod. Express Tools carries SitePro grade rods in metric graduation styles as well.
