The Topcon RL-200 2S Dual Slope Grade Laser Package (314920762-2ET) gives contractors a complete, field-ready solution for precision grading, concrete flatwork, and site preparation. Built around Topcon's proven dual-axis slope technology, this rechargeable package pairs the RL-200 2S rotating laser with the LS-80X machine-control-compatible receiver, an inches-graduated grade rod, and a fiberglass elevator tripod—everything you need to set up and start shooting grade right out of the case.
Package Overview & Jobsite Applications
The RL-200 2S is engineered for contractors who need independent X and Y axis slope control without the complexity or cost of a full machine-control system. With dual-slope capability up to ±10% on both axes simultaneously, this laser handles parking lots, retention ponds, athletic fields, drainage swales, and slab pours where cross-fall and fall-away grades must be dialed in precisely. The self-leveling system compensates automatically within ±5° of level, speeding setup on uneven terrain. Operating range reaches 2,600 ft in diameter (with the included LS-80X receiver), making it equally at home on expansive commercial sites and tight residential lots.

Job Applications
Concrete Flatwork & Slab Pours: Set a consistent dual-slope plane across the entire slab area. Screed crews can verify elevation continuously without stopping for manual checks, reducing low spots and rework.
Parking Lot & Paving Grade: Dial in cross-slope and longitudinal fall simultaneously so water drains to intended catch basins. The high-accuracy dual-axis control keeps ADA-compliant slopes tight across large paved areas.
Drainage, Swales & Retention Basins: Independent X/Y slope settings let operators shape complex drainage geometry in a single setup. The wide operating range covers large detention pond excavations without moving the instrument.
Athletic Fields & Landscape Grading: Achieve consistent crown or fall-away grades across turf areas. The rechargeable battery's 50-hour runtime handles full-day operations without mid-shift recharging delays.

Frequently Asked Questions
- Can the RL-200 2S set different slopes on each axis at the same time?
- Yes. The RL-200 2S allows fully independent slope settings on both the X and Y axes simultaneously, up to ±10% each. This makes it ideal for parking lots, athletic fields, and any surface requiring a compound or two-directional grade in a single instrument setup.
- Is the LS-80X receiver compatible with machine control systems?
- The LS-80X is designed for manual rod work and grade checking, and it outputs a signal compatible with most popular machine control displays and mast receivers. For full automated blade or bucket control, verify compatibility with your specific machine control manufacturer before purchase.
- What does the elevator tripod add to this package?
- The fiberglass elevator tripod includes a crank-up center column that lets you raise or lower the laser head precisely after the tripod legs are set—without disturbing the instrument's level or slope settings. This is especially valuable on sites where you need to fine-tune height to match an existing benchmark without re-leveling from scratch.
- Why choose an inches rod over a metric or tenths rod?
- Inches-graduated rods display readings in feet, inches, and fractions, which directly matches traditional US construction drawings, cut sheets, and field notes. They eliminate mental conversion for crews already working in imperial units, reducing errors on concrete and finish-grade work where fractions of an inch matter.
