The SitePro KS100HVK-4C rotary laser package delivers a complete, field-ready dual-plane leveling system designed for grading crews, site prep contractors, and finish grade operators who need to hit the ground running. Every component in this kit is factory-matched for direct compatibility, eliminating the guesswork of sourcing individual accessories and ensuring your crew is productive from the first setup.
System Overview and Jobsite Applications
Built around SitePro's KS100HV dual-plane rotary laser, the KS100HVK-4C package pairs the instrument with an inches-graduated leveling rod, a heavy-duty tripod, and a rugged carrying case. The horizontal plane capability covers site leveling, drainage grading, and foundation layout across large open areas, while the vertical plane mode supports column plumb checks, wall layout, and squaring structural grids. The inches-graduated rod makes this kit particularly well-suited for US-standard jobsites where decimal-foot or metric readings would create conversion friction on the crew.

Job Applications
Finish Grading and Drainage Slopes: Set the laser on the tripod, dial in your benchmark elevation, and run rod shots across the entire pad to confirm drainage grades before final compaction. The inches rod eliminates on-site conversion when working from engineer plans in fractional format.
Foundation and Footing Layout: Switch to vertical plane mode to project a precise reference plane for squaring building corners, aligning form panels, and checking column plumb over multi-story heights—all with a single instrument setup.
Utility and Pipeline Trenching: Use the detector clipped to a grade rod to maintain consistent invert elevations along trench runs, reducing re-dig cycles and keeping pipe crews moving efficiently without a second person on grade checks.
Concrete Flatwork and Slab Prep: Shoot elevations across the subgrade before placing screed rails to verify uniform bearing depth, and recheck finished slab surface after screeding to confirm tolerance compliance before the pour sets.

Frequently Asked Questions
- Does this package include a laser detector for outdoor use?
- Yes. The KS100HVK-4C kit includes a laser receiver/detector, which is essential for picking up the laser beam in bright daylight conditions at extended ranges. Without a detector, rotary lasers are typically visible only in low-light environments.
- Is the leveling rod in this kit graduated in inches or decimal feet?
- The rod included in the 4C package is graduated in inches and fractions—the US standard format. If your project specifications are in decimal feet or metric, SitePro offers alternate rod options sold separately that are fully compatible with the KS100HV instrument.
- What is the maximum working range of the KS100HV laser?
- With the included detector, the KS100HV covers a working diameter of up to approximately 1,200 feet, making it suitable for large site grading, subdivision infrastructure, and commercial pad work where long rod shots are routine.
- Can the KS100HV be used for both horizontal leveling and vertical alignment on the same job?
- Yes. The KS100HV is a dual-plane instrument that can project both a horizontal reference plane for elevation work and a vertical reference plane for layout and plumb applications. Switching between modes is done at the instrument without additional accessories.
