Topcon RL-200 2S (314920712-1T) Dual Slope Grade Laser Package, LS-80X Receiver, Tenths Rod and HD Tripod - Alkaline

The Topcon RL-200 2S is a professional dual-slope rotating grade laser engineered for contractors who need precise, simultaneous two-axis grade control on demanding job sites. This complete package (SKU: 314920712-1T) ships ready to work, including the LS-80X machine-mountable receiver, a tenths-graduated grade rod, and a heavy-duty tripod—everything your crew needs to hit grade on excavation, concrete, and drainage work from day one.

Dual-Axis Grade Control for Complex Sites

Single-slope lasers force you to reset and re-run when grades change direction. The RL-200 2S eliminates that bottleneck by projecting a grade plane in two axes simultaneously. Set your X and Y slopes once, and the instrument holds them both while you work across the entire site. With a working radius up to 2,600 feet and an automatic self-leveling range of ±5°, the RL-200 2S is equally at home on a dozer blade, a grade checker, or a tripod over a benchmark.

What's in the Kit

• Topcon RL-200 2S Dual Slope Rotating Laser — the core instrument with dual-axis grade control
• Topcon LS-80X Receiver — machine-mountable, 2.4 in. detection window, compatible with dozers, motor graders, and scrapers
• Tenths-Graduated Grade Rod — calibrated in 0.1 ft increments for fast, accurate readings
• Heavy-Duty Tripod — stable aluminum construction, adjustable height for varied setups
• Carrying case, batteries, and operator documentation

Job Applications

Mass Excavation & Earthwork: Set dual slopes once and let machine operators run cuts and fills across the full site without crew interruptions. The LS-80X mounts directly to the blade for grade-on-the-go control.

Concrete Flatwork & Forming: Dial in precise cross-slopes and run-offs for slabs, parking lots, and tilt-up pads. The RL-200 2S holds tight tolerances that satisfy structural and drainage specs simultaneously.

Drainage & Utility Grading: Establish compound drainage slopes on retention ponds, bio-swales, and utility corridors where single-axis lasers fall short. Two-axis control means no guesswork on complex grading plans.

Road Base & Site Prep: From rough grade to finish grade, the RL-200 2S keeps subbase and base course layers on spec across wide roadway cross-sections without repositioning the instrument.

Compatible Accessories

Frequently Asked Questions

Can the RL-200 2S be used on a dozer or motor grader?

Yes. The included LS-80X receiver is designed for machine-mounting and works with most blade-mounted mast systems. The laser projects a wide-radius grade plane that the receiver tracks continuously while the machine moves across the site.

What is the difference between single-slope and dual-slope lasers?

A single-slope laser sets grade in one axis only—useful for simple drainage or flatwork. A dual-slope laser like the RL-200 2S sets independent grades in both the X and Y axes simultaneously, which is essential for compound slopes, parking lot crowns, and complex grading plans.

Does this package include everything I need to start grading?

Yes. The 314920712-1T kit includes the RL-200 2S laser, LS-80X receiver, tenths rod, heavy-duty tripod, batteries, and a carrying case. You can begin horizontal grading work immediately upon arrival without purchasing additional components.

What is the accuracy of the Topcon RL-200 2S?

The RL-200 2S delivers accuracy of ±1/16 inch at 100 feet (±1.5 mm at 30 meters), which meets or exceeds the tolerance requirements for most earthwork, concrete flatwork, and site grading specifications.
