The SitePRO 28-KS2LG Laser-1 is a professional-grade green beam crossline laser engineered for contractors who demand precision and visibility under real job-site conditions. Projecting both a horizontal and vertical line simultaneously, this tool eliminates the guesswork from interior layout, partition framing, tile setting, and concrete formwork. The green wavelength — four times brighter than conventional red beam lasers — cuts through ambient daylight and artificial lighting so your crew can read the line clearly without hunting for a detector in bright conditions.
Crossline Laser Built for the Full Range of Job-Site Work
Whether you're squaring a room for floor tile, plumbing a door opening, or aligning suspended ceiling grid, the 28-KS2LG delivers a sharp, bright reference line from a compact, self-leveling platform. The unit automatically compensates for minor surface irregularities within its self-leveling range, getting your crew on layout faster without manual adjustments. When you need to project a fixed angle or lock the beam for a raked application, the manual mode locks lines in place for precise off-level work.

Job-Site Applications
- Interior Partition Framing: Shoot a plumb vertical line from floor to ceiling to locate stud centers, door openings, and wall offsets across multiple trades working simultaneously.
- Floor & Wall Tile Layout: Establish perpendicular reference lines in a single setup to keep grout joints square across large format tile installations.
- Suspended Ceiling Grid: Project a level horizontal line around the perimeter of a room to set wall angle iron at consistent height before running main tees.
- Concrete Formwork & Foundation Layout: Use the bright green beam outdoors to transfer control lines to form panels and verify plumb faces before pours.

Frequently Asked Questions
- Does the SitePRO 28-KS2LG work outdoors in bright sunlight?
- Yes — the green 520nm beam is four times brighter than a standard red laser and is visible in many outdoor conditions unaided. For full outdoor range in direct sunlight, pair the unit with a compatible SitePRO green beam detector to achieve reliable readings beyond 30 feet.
- Can I use the 28-KS2LG to project a single line instead of both lines at once?
- Yes. The 28-KS2LG allows you to activate the horizontal line, the vertical line, or both simultaneously, giving you the flexibility to isolate the reference you need for each specific task without unnecessary beam clutter on the wall.
- What happens if the laser is set up on a surface that is more than 4° out of level?
- If the tilt exceeds the ±4° self-leveling range, the unit will flash or sound an alert to indicate it cannot self-level accurately. In this case, shim the base or use an adjustable tripod to bring the unit within the leveling window before use.
- Is the 28-KS2LG compatible with standard contractor tripods?
- Yes. The base of the 28-KS2LG features a standard 5/8-11 threaded mount, which is compatible with the vast majority of contractor-grade laser tripods, grade rods, and adjustable wall brackets available on the market.
