The Topcon RL-200 2S Dual Slope Grade Laser Package (314920762-1ET) is a fully equipped grading system built for contractors who need reliable, repeatable dual-axis slope control on demanding job sites. This package pairs the industry-trusted RL-200 2S rotating laser with the LS-80X digital receiver, a fiberglass elevator tripod, and a tenths rod — everything needed to set grade and move dirt or concrete from day one. Whether you're forming flatwork, cutting sub-base, or grading drainage swales, the RL-200 2S delivers the accuracy and durability professional crews depend on.
System Overview & Jobsite Applications
The Topcon RL-200 2S is engineered for contractors who regularly work dual-slope applications — setting cross-slopes on parking lots, crowning roadways, grading retention basins, or establishing compound fall on concrete slabs. Its self-leveling range and dual-axis slope capability eliminate the manual calculation and repeated setup checks that slow production. The included elevator tripod adds a critical advantage: precise height adjustment via a geared crank mechanism, letting operators lock exact elevation without disturbing the instrument's level or slope settings. The LS-80X digital receiver provides clear grade indication in all light conditions, and the tenths rod ensures accurate staff readings throughout the work area.

Job Applications
Concrete Flatwork & Tilt-Up: Set dual slopes across large slab pours to ensure proper drainage fall without re-checking grade with a hand level. The LS-80X receiver mounted to a screed or laser-guided roller keeps the entire crew on grade simultaneously.
Parking Lot & Roadway Sub-Base: Establish cross-slope and longitudinal grade simultaneously when preparing aggregate base for asphalt. The RL-200 2S holds both X and Y slopes independently, eliminating re-setup when grade direction changes.
Retention Basin & Site Drainage Grading: Program compound slopes to direct stormwater runoff precisely to inlets. The 800m operating range keeps the instrument stationary while machine operators work across the full basin.
Elevated Deck & Elevated Slab Work: The elevator tripod's crank-adjust mechanism allows fine elevation changes when setting form height on elevated decks or bridge approaches — critical when a few millimeters of error affects drainage performance.

Frequently Asked Questions
- Can the RL-200 2S set independent slopes on both axes simultaneously?
- Yes. The RL-200 2S allows you to program separate grade percentages on the X and Y axes independently. This makes it ideal for parking lots, roadway crowns, and retention basins where compound slopes are required without resetting the instrument between axes.
- What is the advantage of the elevator tripod over a standard tripod?
- The elevator tripod includes a geared crank mechanism on the center column that allows fine, precise height adjustment after coarse leg positioning. This is especially useful when matching an exact benchmark elevation or making small height corrections without disturbing the laser's level or slope settings.
- How long does the rechargeable battery last in the field?
- The RL-200 2S rechargeable battery pack provides up to 60 hours of continuous operation under normal conditions. For extended projects or multi-shift work, a spare battery pack is recommended to eliminate downtime.
- Is the Topcon RL-200 2S compatible with machine control systems?
- The RL-200 2S is primarily designed for staff and receiver-based grade control. For full machine control integration (motor grader, dozer blade), Topcon's 3D machine control systems are recommended. However, the LS-80X receiver can be used with grade-control masts on some light-duty applications. Contact Express Tools for compatibility details specific to your equipment.
