Topcon RL-HV2S Self-Leveling Dual Grade Laser Complete Kit with LS-100D Receiver, Inches Rod and Tripod / Rechargeable

The Topcon RL-HV2S Kit (SKU: 1051612-22-K2) delivers professional-grade dual-axis slope control for contractors who demand accuracy and reliability across the most demanding grading, drainage, and layout applications. As an authorized Topcon dealer, Express Tools supplies this complete system ready to work right out of the case — no additional purchases required to get your crew productive on day one.

Product Overview

The RL-HV2S is Topcon's workhorse dual-grade rotary laser, engineered for contractors handling complex slope work including cross-slopes, crowned road surfaces, ADA-compliant flatwork, and multi-directional drainage systems. Unlike single-grade lasers that set slope in only one direction, the RL-HV2S simultaneously controls grade on both the X and Y axes, eliminating setup time and reducing the risk of layout errors on compound graded surfaces. With a self-leveling range of ±5° and dual-grade capability up to ±10% in each axis, this unit handles everything from gentle parking lot drainage pitches to aggressive cut-and-fill operations.

Job Applications

Site Grading & Earthwork: Set dual-axis slopes across large cut-and-fill sites with a single instrument setup. Machine operators and grade checkers work simultaneously off the same reference plane, keeping the job moving.

Parking Lots & Flatwork: Achieve precise cross-slope drainage gradients that meet ADA and local code requirements without constant re-staking. The LS-100D receiver gives concrete and asphalt crews a fast, readable grade signal at the screed or blade.

Road Construction & Crowned Surfaces: The X/Y dual-grade function is purpose-built for crowned road profiles and superelevated curves where single-slope tools simply can't keep up.

Underground Utility & Drainage Pipe: Set consistent fall on sewer, stormwater, and irrigation lines. The high-accuracy beam and long working range keep layout moving on large subdivisions and commercial sites.

Frequently Asked Questions

What is the difference between the RL-HV2S and a standard single-grade laser?

A standard single-grade laser sets slope in only one direction at a time. The RL-HV2S simultaneously controls grade on both the X and Y axes, allowing you to establish compound slopes — such as a crowned road or a parking lot draining to a corner catch basin — in a single setup without moving or re-leveling the instrument.

Does the RL-HV2S kit include everything needed to start working on-site?

Yes. The 1051612-22-K2 kit includes the RL-HV2S laser, LS-100D receiver, aluminum tripod, inches grade rod, rechargeable battery pack with charger, and a carrying case. No additional equipment is required to begin grading or layout operations right away.

Is the LS-100D receiver compatible with other Topcon lasers?

The LS-100D is designed to work with the full range of Topcon rotary lasers and is also cross-compatible with many other manufacturers' red-beam rotary laser instruments. For specific compatibility questions, contact the Express Tools product team.

What is the IP66 rating and why does it matter on a job site?

IP66 means the RL-HV2S is fully protected against dust ingress and powerful water jets from any direction. On active construction sites where equipment is exposed to rain, mud, concrete splash, and heavy dust, an IP66 rating ensures the laser continues operating accurately without damage to internal components.
