The SitePro 27-LR410H-4T is a complete horizontal rotary laser leveling system built for contractors, survey crews, and equipment operators who demand fast setup and precise elevation control on every job. This package bundles the rugged SitePro LR410H rotary laser with a 13-foot tenths-graduated measuring rod and an adjustable aluminum tripod — giving you everything you need to get on grade from the first setup. With tool-free leveling, wide working range, and a durable field-ready design, the LR410H-4T eliminates the need to piece together a system and gets your crew working faster.
Overview & Jobsite Applications
The SitePro LR410H is engineered for horizontal plane leveling across a wide range of civil construction and grading applications. Its self-leveling mechanism compensates for minor instrument movement, keeping your reference plane accurate throughout the workday. The included tenths rod is calibrated in 0.1-foot increments — the standard unit of measurement used by graders, operators, and surveyors on elevation-controlled projects. Whether you're setting a building pad, establishing drainage grades, or shooting elevations for a site plan, this system delivers the accuracy and reliability professionals require.

Job Applications
Site Grading & Earthwork: Set and verify finish grades across large cut-and-fill sites. The tenths rod reads directly in the decimal feet your grade sheets call out — no conversion needed for operators running scrapers or motor graders.
Building Pad Layout: Establish a level reference plane for concrete pads, footings, and slabs. The LR410H's 1,000-ft working radius covers large commercial pads without repositioning the instrument.
Drainage & Utility Slope: Use the laser and tenths rod together to confirm invert elevations, storm drain grades, and swale cross-sections against plan elevations with speed and confidence.
Surveying & Elevation Checks: Survey crews and inspectors can use the system to shoot spot elevations for quantity tracking, as-built verification, or pre-construction topo checks — all in tenths for direct plan comparison.

Frequently Asked Questions
- Does the SitePro 27-LR410H-4T work outdoors in bright sunlight?
- Yes. The LR410H is designed for outdoor use and pairs with a laser detector/receiver for bright-light conditions where the beam is not visible to the naked eye. The included or compatible detector picks up the laser signal at distances up to 1,000 feet, making it fully functional on open grading sites in direct sunlight.
- What does "tenths" mean on the measuring rod?
- Tenths refers to graduations in tenths of a foot (0.1 ft increments), which is the standard unit used in civil construction, grading, and surveying. Reading elevations in decimal feet lets operators and surveyors match plan elevations directly without converting from inches — a critical time-saver on graded sites.
- Is the tripod adjustable for uneven terrain?
- Yes. The included contractor-grade aluminum tripod has individually adjustable legs that can be set to different heights, allowing you to level the instrument on sloped or uneven ground. The tripod pairs with the LR410H's self-leveling mechanism to establish an accurate horizontal plane quickly.
- Can I use this laser level for indoor work like setting drop ceilings or floor leveling?
- The LR410H is primarily optimized for outdoor horizontal leveling over long distances. While it can function indoors, its large working radius and outdoor-focused design make it best suited for site grading, earthwork, and civil construction applications. For interior finish work, a smaller rotary or line laser may be more practical.
