Site-Pro 11-SCR13-C 13-foot Fiberglass Rectangular Series (CR) — Inches Graduations

Site-Pro 11-SCR13-C Fiberglass Leveling Rod

The Site-Pro 11-SCR13-C is a contractor-grade fiberglass leveling rod built to handle the daily rigors of site grading, elevation transfer, and laser-level operations. Extending to a full 13 feet, this rod gives field crews the vertical range needed for most residential and light commercial leveling tasks without the bulk of a larger staff. Whether you are shooting grades across a freshly stripped pad or checking floor elevations inside a framed structure, the SCR13-C delivers clear, readable graduations and solid construction you can count on shift after shift.

Overview & Jobsite Applications

Designed for professional surveyors, grade checkers, and construction superintendents, the SCR13-C pairs with optical levels, automatic levels, and rotating laser receivers to streamline elevation control on active jobsites. Its fiberglass construction resists the warping and swelling that plague wood rods in wet or humid conditions, maintaining graduation accuracy throughout the season. The high-contrast inch and eighths markings allow instrument operators to obtain readings quickly, reducing crew downtime and minimizing miscommunication between the rod person and the level operator.

Key Specifications

• Model: Site-Pro 11-SCR13-C
• Extended Length: 13 feet
• Graduation Increments: Inches and eighths of an inch
• Rod Material: Fiberglass composite
• Construction Type: Telescoping / slip-joint sections
• Graduation Style: High-contrast printed scale for fast optical reading
• Intended Use: Optical levels, automatic levels, laser receivers

Key Features

• Fiberglass construction eliminates moisture-related warping for year-round accuracy
• 13-foot length covers standard elevation differentials on grading and foundation projects
• Inch and eighths graduation markings compatible with most construction-grade optical instruments
• Lightweight sections allow a single crew member to carry and set up without assistance
• Slip-joint locking mechanism keeps extended sections firmly in place during readings
• High-visibility scale markings reduce misread elevations in low-light or high-glare conditions
• Durable printed graduations resist fading from UV exposure and field abrasion

Job Applications

Site Grading & Earthwork: Use the SCR13-C with a rotating laser or automatic level to verify cut-and-fill elevations across graded pads, driveways, and drainage swales. The 13-foot reach handles most single-story cut depths without switching equipment.

Foundation Layout & Footing Checks: Confirm footing depths and bearing elevations during foundation excavation. The clear inch-and-eighths scale lets the instrument operator call elevations directly to the excavator operator without conversion delays.

Floor & Structural Elevation Surveys: Inside framed structures, shoot floor-to-floor elevations or verify structural bearing points. The rod's manageable length navigates interior spaces more easily than longer staffs.

Utility & Pipeline Grade Control: Set or verify pipe invert elevations during storm drain, sanitary sewer, or water main installation. Pair with a laser receiver on the rod for hands-free grade checking during trenching operations.

Compatible Accessories

• Laser Rod Clamp / Receiver Bracket — Mounts a laser receiver at any point along the rod for grade-checking during excavation
• Rod Level / Bullseye Bubble — Ensures the rod is plumb for accurate elevation shots
• Automatic Optical Level — Pairs directly with the SCR13-C for traditional differential leveling
• Rotating Laser Level — Combine with a laser receiver clipped to the rod for one-person grade work
• Rod Target / Rod Face — High-contrast target for long-distance or low-visibility readings

Frequently Asked Questions

What graduation units does the SCR13-C use?

The SCR13-C is graduated in inches and eighths of an inch, making it compatible with standard U.S. construction-grade optical and laser leveling instruments. This graduation system allows direct elevation readings without conversion when working in feet and inches.

Can I use the SCR13-C with a laser receiver?

Yes. The SCR13-C can be used with a clip-on or bracket-mounted laser receiver. When paired with a rotating laser level and receiver, one crew member can perform grade checks independently, which is common practice on grading and utility installation projects.

Is fiberglass better than aluminum for a leveling rod?

Fiberglass offers better dimensional stability in wet or humid environments because it does not absorb moisture or expand the way wood does, and it resists the minor flexing that can affect thin aluminum rods. For most field grading and survey applications, fiberglass is the preferred material for long-term graduation accuracy.

How do I extend and lock the sections on the SCR13-C?

The SCR13-C uses a slip-joint locking system. Pull each section to the desired extension and tighten the locking collar or clamp at each joint until the section is firmly secured. Always verify the section is fully seated and locked before taking a rod reading to prevent inaccurate elevation shots caused by an unintended partial extension.
