The Topcon RL-200 2S Dual Slope Grade Laser Package (314920712-2ET) gives contractors a complete, field-ready grading solution with fast, precise height adjustment. This kit pairs the RL-200 2S rotating laser with the LS-80X laser receiver, an inches grade rod, and an elevator tripod — everything needed to set accurate dual-slope grades on interior concrete pours, site grading, drainage work, and multi-level construction projects. If your crews frequently relocate the instrument or work at varying elevations, the elevator tripod's center column crank makes repositioning fast without breaking your grade setup.
Topcon RL-200 2S: Dual Slope Grading Performance
The RL-200 2S is a professional-grade self-leveling rotating laser built specifically for contractors who need independent X and Y axis slope control. Set slopes from 0% to 25% on both axes simultaneously — ideal for crowned parking lots, ADA-compliant ramps, drainage swales, and sloped concrete slabs. The instrument self-levels within a ±5° range, reducing setup time on uneven ground. With a working radius of up to 800 meters (diameter) using the LS-80X receiver, the RL-200 2S handles large jobsite footprints without repositioning. IP66-rated housing keeps it operational through rain, dust, and heavy jobsite environments.

Job Applications
Interior Concrete Floors: Pour and screed to precise grade across large slab areas. The elevator tripod lets you dial in instrument height quickly between pours without re-establishing your benchmark.
Site Grading and Earthwork: Set dual-axis slopes for parking lots, athletic fields, and landscaped areas in a single instrument setup. Machine operators and rod crews work simultaneously with grade information broadcast across the full site.
Drainage and Utility Work: Establish consistent fall grades for stormwater swales, pipe trenches, and retention basin floors where both cross-slope and longitudinal grade must be controlled.
Multi-Level and Elevated Work: The elevator tripod's adjustable column height makes the RL-200 2S practical on elevated decks, mezzanines, and tiered site work where fixed-leg tripods require time-consuming repositioning.

Frequently Asked Questions
- Can the RL-200 2S set slope on both axes at the same time?
- Yes. The RL-200 2S independently controls X-axis and Y-axis slope from 0% to ±25% simultaneously, making it suitable for crowned surfaces, compound drainage grades, and ADA ramp work in a single setup.
- What is the advantage of the elevator tripod over a standard tripod?
- The elevator tripod's center column crank lets you raise or lower the instrument without adjusting the tripod legs, which preserves your level setup. This is particularly valuable on interior pours and multi-level sites where instrument height changes frequently.
- Is the RL-200 2S compatible with machine control systems?
- The RL-200 2S broadcasts a standard rotating laser plane compatible with most laser-ready grade control systems. For full machine control integration, contact Express Tools to confirm compatibility with your specific machine control receiver or system.
- How long do batteries last in the Topcon RL-200 2S?
- The RL-200 2S runs up to 100 hours on standard D-cell batteries at normal rotation speeds. Battery life varies with rotation speed and temperature, but the instrument is designed for full-day operation without mid-shift battery changes under typical jobsite conditions.
