SitePro 27-LR430HDV-4C Horizontal Rotary Laser Package
The SitePro 27-LR430HDV-4C is a professional-grade horizontal rotary laser package engineered for contractors who need a complete, field-ready grade control and layout system out of the box. Combining the high-performance LR430HDV dual-plane laser transmitter with a heavy-duty aluminum tripod and a 16-foot grade rod graduated in inches, this kit eliminates the time and cost of sourcing compatible accessories separately. Whether you're a grading contractor establishing finish elevations, a site superintendent setting drainage slopes, or a concrete flatwork crew laying out floor grades, the LR430HDV-4C delivers the accuracy, range, and durability that professional field conditions demand.
System Overview and Jobsite Applications
The LR430HDV transmitter operates on a self-leveling platform that compensates for minor out-of-level conditions automatically, letting crews set up fast and get to work without fussing with fine adjustments. With a working range suitable for large commercial and civil sites, the system supports single-operator workflows where one person manages grade while another handles the rod. The included digital grade rod with inch-scale markings is calibrated for use with the SitePro receiver, allowing for quick, readable elevation calls across the site. The aluminum tripod provides a stable, adjustable base that performs reliably on uneven terrain and holds its set height through the vibrations and environmental changes of an active jobsite.

- Remote Control — wireless remote for operating rotation speed, power, and other functions from the rod position
Job Applications
The SitePro 27-LR430HDV-4C is purpose-built for the kinds of tasks that demand reliable elevation control on active construction sites. Here are four common applications where this system earns its keep:
- Site Grading and Earthwork: Set finish grade elevations for parking lots, building pads, and roadway subgrades. The extended working range lets one operator control large areas, and the detector mounts directly to the included grade rod for hands-free readings while running equipment.
- Concrete Flatwork and Slabs: Establish precise floor elevations for warehouse slabs, tilt-up panels, and residential foundations. Contractors use the laser plane to verify screed heights, set form grades, and check elevation consistency across large pours before the concrete goes down.
- Drainage and Utility Layout: Control positive drainage slopes for parking areas, drainage swales, and storm sewer invert elevations. The grade function allows contractors to set consistent slope across long runs without resetting instrument height.
- Interior Framing and Suspended Ceilings: Switch the transmitter to a slower rotation speed for interior layout tasks including dropped ceiling grid elevation, door and window header heights, and partition wall layout where a consistent reference plane speeds up work across large floor plates.

Frequently Asked Questions
- Does the LR430HDV-4C kit include a laser detector, or do I need to purchase one separately?
- Yes, the 27-LR430HDV-4C package includes a compatible laser detector/receiver with a rod clamp. The detector mounts to the included 16-foot grade rod and provides audible and visual grade indication for one-person operation. No additional detector purchase is required to begin working immediately on delivery.
- What is the effective working range of the SitePro LR430HDV transmitter?
- With the included detector, the LR430HDV operates effectively at working diameters up to approximately 2,600 feet (800 meters), making it well-suited for large grading sites, commercial parking lots, and expansive building pads. Visual-only range without a detector is significantly shorter and intended for close-range interior applications.
- Can I use the LR430HDV to set grades and slopes, or is it a flat-plane only instrument?
- The LR430HDV supports manual grade adjustment on the horizontal axis, allowing contractors to set a consistent slope reference plane for drainage, subgrade preparation, and flatwork layout. Grade is set manually via the instrument controls. For precision automated grade matching, a machine control receiver mounted to grading equipment can be paired with the transmitter.
- Is the SitePro 27-LR430HDV-4C covered by a manufacturer warranty, and what does it include?
- SitePro backs the LR430HDV transmitter with a manufacturer's limited warranty covering defects in materials and workmanship. As an authorized SitePro dealer, Express Tools supports warranty service and can facilitate repairs or replacements as needed.
