The Topcon RL-200 2S (314920762-2T) is a professional-grade dual slope rotating laser designed for contractors who demand precision on grading, concrete flatwork, and site preparation jobs. This complete kit pairs the RL-200 2S laser with the LS-80X digital receiver, an inches-graduated grade rod, and a heavy-duty tripod — giving you everything needed to set up and control grade from the moment you arrive on site. The rechargeable power system eliminates battery replacement costs and keeps the unit running through full production days.
Overview & Jobsite Applications
Built for the demands of exterior grading and concrete work, the RL-200 2S delivers independent dual-axis slope control with a range of up to 2,000 feet in diameter. Whether you're cutting drainage swales, establishing parking lot grades, or pouring sloped concrete slabs, this system gives your crew a reliable, fast-locking grade reference without manual conversions. The inches rod format matches the way most field crews already work — read elevations in feet, inches, and fractions without decimal conversion math slowing down production.

Job Applications
Drainage & Lot Grading: Set precise cross-slopes and fall lines across large sites. The dual-axis slope control handles complex drainage designs in a single setup, reducing instrument moves and saving time.
Concrete Flatwork & Slabs: Establish accurate slope on driveways, warehouse floors, loading docks, and sloped slabs. Screed rails and forms can be set quickly using the LS-80X receiver's clear digital readout.
Road Base & Subgrade Prep: Control blade elevation and cross-slope on motor graders or skid steers. The 2,000 ft operating range keeps the laser relevant even on wide roadway sections.
Utility Trench Slope: Use the grade rod and receiver to verify pipe fall and trench bottom elevation at each station, ensuring code-compliant slope without pulling strings.

Frequently Asked Questions
- Can the RL-200 2S set different slopes on both axes simultaneously?
- Yes. The RL-200 2S features independent dual-axis slope control, allowing you to set a unique grade percentage on both the X and Y axes at the same time. This makes it ideal for complex drainage planes and sloped concrete applications that require a true dual-pitch layout.
- What is the maximum slope range on the RL-200 2S?
- The RL-200 2S supports a slope range of ±10% on both axes. This covers the vast majority of grading and flatwork applications encountered in commercial and residential site work.
- Does this kit work with a machine control system or grade indicate setup?
- The LS-80X receiver included in this kit is designed for hand-held and rod-mounted use. For machine control or blade-mounted grade indicate applications, Topcon offers compatible machine receivers and mounting hardware sold separately. Contact Express Tools for guidance on machine control integration.
- How long does the rechargeable battery last on a full charge?
- The RL-200 2S rechargeable battery pack provides up to 50 hours of continuous operation on a single charge under normal conditions. The charger is included in the kit, and replacement battery packs are available if you need a spare for extended shifts.
