The Topcon RL-H5A (1021200-16-BCC) delivers the proven horizontal leveling performance contractors rely on — packaged as a bare tool with a rechargeable battery so you can integrate it directly into your existing equipment setup. Whether you're building out a multi-laser crew, replacing a damaged unit, or standardizing around a single receiver platform across your fleet, this configuration lets you skip paying for accessories you already own. Purchased from Express Tools, an authorized Topcon dealer, every RL-H5A is backed by Topcon's full factory warranty.
Horizontal Self-Leveling Laser for Demanding Jobsites
The RL-H5A is engineered for horizontal-plane applications where accuracy and runtime matter. With an automatic self-leveling range of ±5° and a 600-meter diameter working range (with a compatible receiver), it handles everything from residential slab pours and finish grading to commercial interior layout and utility trenching. The IP66-rated housing resists dust and water ingress, keeping the tool running through concrete dust, rain, and the general abuse of active construction sites. Topcon's STICS (Slope Tilt Indicator and Compensation System) sensor technology provides stable, consistent beam output even on slightly uneven setups.

Job Site Applications
The RL-H5A is built for horizontal-plane work across a wide range of trades and project types:
- Concrete Flatwork & Slabs: Set consistent pour heights across large slab areas with a single laser reference plane — no re-checking grade stakes between pours.
- Finish & Rough Grading: Pair with a grade rod and LS-100D or LS-80L receiver for fast, accurate cut/fill readings across open excavation sites.
- Interior Layout & Drop Ceilings: Establish level reference lines for suspended ceiling grids, partition walls, and MEP rough-in at any rotation speed.
- Utility Trenching & Site Drainage: Use in scan mode with a compatible receiver to maintain consistent trench bottom grades across long runs without constant re-staking.

Frequently Asked Questions
- Does this kit include a laser receiver?
- No. The 1021200-16-BCC is a bare tool configuration that includes only the RL-H5A laser head, rechargeable battery, charger, and carrying case. A compatible receiver such as the Topcon LS-100D or LS-80L must be purchased separately for outdoor use beyond unaided visible range.
- Can the RL-H5A be used for vertical or grade (slope) applications?
- The RL-H5A is a horizontal-only rotary laser and does not support slope or grade mode. If you require single- or dual-axis grade capability, consider the Topcon RL-H5B, which adds a motorized grade function.
- What is the battery runtime on a full charge?
- Topcon rates the included Li-Ion battery pack at up to 40 hours of continuous use at standard rotation speeds. Actual runtime varies with rotation speed setting, temperature, and battery age. A spare battery pack is available separately for high-volume or multi-shift operations.
- Is this an authorized Topcon product with full warranty coverage?
- Yes. Express Tools is an authorized Topcon dealer, and all RL-H5A units sold through our store carry Topcon's full factory warranty. Gray-market or unauthorized units may not qualify for warranty service or factory support — always verify dealer authorization before purchasing professional laser equipment.
