SitePro KS-Series Cross Line Green Beam Laser

The Topcon RL-200 2S Dual Slope Grade Laser is built for contractors who need precision grade control across complex, multi-slope job sites. With independent dual-axis slope capability and a 25% maximum slope rating, this rotary laser handles everything from aggressive drainage channels to finish grading on commercial developments—without tearing down and resetting between phases. Paired with the included LS-80X laser receiver, the RL-200 2S delivers reliable performance across long ranges in both bright daylight and low-light conditions.

Overview: Engineered for Complex Grading Work

Site grading rarely involves a single consistent slope. The RL-200 2S addresses that reality by allowing contractors to set and switch between independent X- and Y-axis grades directly in the field. Whether you're managing drainage swales that intersect at opposing grades, establishing foundation footings on sloped terrain, or finishing parking lot surfaces that require simultaneous cross and running slopes, the RL-200 2S eliminates the downtime of repeated instrument repositioning. Its robust construction is rated for demanding outdoor conditions, making it a dependable tool across seasons and site types.

Job Site Applications

Site Drainage and Swale Grading: Set opposing cross-slopes and running grades simultaneously to establish positive drainage across parking lots, athletic fields, and commercial pads without repeated instrument moves.

Foundation and Footing Layout: Maintain consistent elevation control across sloped building pads where both longitudinal and transverse grades must be held concurrently.

Finish Grading and Subgrade: Use the LS-80X receiver in combination with a grade rod for single-person finish grading verification across large areas, reducing labor cost on final-pass work.

Agricultural and Land Leveling: The 25% slope ceiling makes the RL-200 2S suitable for terraced agricultural grading, retention pond construction, and land-forming projects where steep grade transitions are routine.

Frequently Asked Questions

Can the RL-200 2S set slopes on both axes at the same time?

Yes. The RL-200 2S supports true simultaneous dual-slope operation, allowing you to dial in independent grade values on both the X and Y axes concurrently. This is essential for applications like parking lot drainage where cross-slope and running slope must both be controlled in a single setup.

What is the maximum slope the RL-200 2S can handle?

The RL-200 2S supports up to ±25% grade on each axis, which equates to approximately a 1:4 rise-to-run ratio. This range covers the vast majority of civil grading, drainage, and foundation applications encountered in commercial and residential site work.

Does the LS-80X receiver work in direct sunlight?

Yes. The LS-80X is designed for outdoor use and features a high-visibility LED display and audible grade indicators that allow single-operator use in bright daylight conditions. For extreme range work in high ambient light, selecting a slower rotation speed on the RL-200 2S can also improve receiver sensitivity.

Is the Topcon RC-200 remote control included with the RL-200 2S?

The RC-200 wireless remote is not included in the standard kit but is sold separately and is fully compatible with the RL-200 2S. It allows you to adjust grade settings and control the instrument from the machine cab or grade rod position, which is particularly useful for solo grading operations.
