Self-Leveling Rotary Laser for Interior and Exterior Leveling
The Topcon RL-H5A (model 1021200-07) is a horizontal self-leveling rotary laser designed for general construction, concrete forming, and layout applications. This PS.DB kit includes the LS-80L digital laser receiver with clamp and runs on standard alkaline D-cell batteries, making it ideal for contractors who prefer the convenience and availability of disposable batteries over rechargeable packs.
Who Uses the RL-H5A
This laser is a workhorse for concrete crews setting forms and screeds, drywall contractors establishing ceiling grids, and site layout teams transferring elevations across footings and slabs. It's equally effective indoors for suspended ceiling installation and outdoors for rough grading and foundation layout. The RL-H5A offers the leveling performance and durability professional crews expect without the cost and complexity of dual-slope or machine-control models.
Key Performance Specifications
The RL-H5A self-levels within ±5 degrees and provides horizontal accuracy of ±1/16 inch at 100 feet (±1.5 mm at 30 meters). The rotating head delivers a 360-degree level reference plane visible with the included LS-80L receiver at distances up to 2,600 feet (800 meters) in diameter. The laser features variable rotation speeds from 0 to 600 RPM, allowing you to adjust beam visibility and battery life based on job conditions.
Alkaline Battery Operation
This PS.DB (alkaline battery) version of the RL-H5A runs on four D-cell alkaline batteries, which are available at any hardware store or job site supplier. This eliminates the need to manage rechargeable battery packs and chargers, making it a practical choice for contractors who run multiple laser units across different crews or who work in remote locations without reliable access to charging infrastructure. Expect 60-100 hours of runtime per battery set depending on rotation speed and temperature.

LS-80L Receiver Features
The LS-80L is a digital laser detector with a large LCD readout and audible tone guidance. It provides on-grade indication and displays high/low reference, making it easy for operators to set grade stakes, level concrete screeds, or align formwork quickly and accurately. The receiver mounts on grade rods, machine masts, or the included clamp for hands-free operation.
