PRODUCT OVERVIEW

Product Description

The Topcon RL-H5A DB2 (model 1021200-50-K2) is a contractor-grade self-leveling rotary laser built for dependable horizontal grade work across a wide range of jobsite conditions. Whether you're establishing building elevations, checking subgrade, or laying out site drainage, the RL-H5A delivers consistent ±10 arc-second accuracy without requiring complex setup or specialized training. This complete kit pairs the laser with the LS-80X digital grade readout receiver, an inch-graduated measuring rod, and a rugged aluminum tripod—everything you need to start working the moment you arrive on site.

Built for Everyday Contractor Work

The RL-H5A is engineered for horizontal leveling tasks that demand reliability over a full shift. Its 600-meter diameter working range (with receiver) handles large open sites with ease, while the automatic self-leveling system gets the laser planed and spinning in seconds. Powered by standard AA alkaline batteries—not proprietary rechargeable packs—the RL-H5A keeps you running without battery management headaches. The IP66-rated housing resists dust ingress and direct water jets, so a passing rain shower or dusty grading operation won't take you off the clock.

What's Included in the Kit

Topcon RL-H5A DB2 Rotary Laser — self-leveling horizontal laser unit
Topcon LS-80X Digital Receiver — audio and digital grade readout, 600 m range
Aluminum Tripod — adjustable contractor-grade tripod for stable setup
Inch-Graduated Measuring Rod — direct-read rod for elevation and grade checks
Carrying Case — protective storage for transport and site use
Batteries — AA alkaline batteries included
Operator Manual — English setup and operation guide

Job Applications

Site Grading & Earthwork: Set cut/fill elevations quickly across large open sites. The LS-80X receiver mounts to a grade rod so operators can check grade independently without a second person at the instrument.

Foundation & Footing Layout: Establish consistent elevation benchmarks around a foundation perimeter. The ±10 arc-second accuracy keeps footing elevations within tight tolerances on residential and light commercial work.

Drainage & Utility Slope: Use the single-axis slope mode to set consistent fall on drainage swales, parking lot runoff, and shallow utility trenches without the need for a dual-grade instrument.

Interior Finish Work: Level suspended ceilings, set floor screeds, and verify slab flatness. The selectable low rotation speed (300 RPM) produces a bright, visible reference line for indoor applications.

Compatible Accessories

Topcon LS-80L Receiver — long-range receiver for large open sites
Topcon RC-40 Remote Control — wireless rotation and slope adjustment from the rod
Topcon RD-1 Detector Bracket — universal rod-mount bracket for LS-series receivers
Replacement AA Battery Pack — alkaline battery bundle for extended field use
Heavy-Duty Aluminum Tripod Upgrade — higher-capacity tripod for uneven terrain

Frequently Asked Questions

Does the Topcon RL-H5A work outdoors in bright sunlight?: Yes. The RL-H5A is designed for outdoor use and works most effectively outdoors when paired with the included LS-80X receiver, which detects the laser signal even in direct sunlight far beyond what the naked eye can see. The receiver's audible and digital grade readout eliminates any reliance on visual beam detection in high-ambient-light conditions.
Can the RL-H5A set slope grades, or is it horizontal only?: The RL-H5A DB2 supports single-axis slope mode with a grade range of 0–25%. This allows you to tilt the laser plane along one axis to match a specified grade percentage, which is useful for drainage, road crown, and utility trench applications. It does not support dual-axis (X/Y) simultaneous slope.
What batteries does the RL-H5A use, and how long do they last?: The RL-H5A runs on four standard AA alkaline batteries available at any hardware or convenience store. Topcon rates battery life at approximately 100 hours of continuous operation, which translates to several weeks of typical contractor use. There are no proprietary rechargeable packs to manage or replace.
Is the RL-H5A covered by a Topcon warranty?: Yes. As an authorized Topcon dealer, Express Tools sells the RL-H5A with the full Topcon manufacturer warranty. Topcon backs this instrument with a three-year warranty on parts and labor when purchased through authorized channels. Warranty service is handled through Topcon's North American service network.

Why This Equipment

Auto Self-Leveling

Compensates for job site movement and setups — no manual leveling required.

Long Range

Reach 2,600+ ft with a receiver — covers large pads and site-wide grading without moving.

IP55+ Protection

Dust-tight and water jet resistant — built for outdoor construction in any weather.

Radio Remote

Change grade or elevation from the cab or anywhere on site without walking back.

Why Buy This?

The right rotary laser pays for itself in weeks.

A grade checker costs $600–800 per day. A quality rotary laser setup eliminates that cost indefinitely — and works faster. One operator with a good laser and receiver can cover ground that used to take a two-person crew.

The gap between a budget unit and a professional-grade one shows up in the field: self-leveling range on uneven pads, IP55+ protection through rain and dust, and radio remote control so you're not walking back to the instrument every time the job moves.

Express Tools is an authorized dealer with genuine, factory-fresh inventory and same-day shipping on in-stock units. We know this equipment and can answer spec questions before you order.
