Complete Dual-Slope Rotary Laser System for Grade Work and Vertical Layout
The Topcon RL-HV2S (model 1051612-17) is a professional-grade horizontal and vertical dual-axis rotary laser system built for contractors who need accurate slope control and versatile layout capability on a single instrument. This kit bundles the RL-HV2S laser with the LS-100D digital receiver and the Holder 110 rod clamp, giving you everything needed to hit the ground running on grading, forming, framing, and alignment jobs without sourcing components separately.
Overview and Jobsite Applications
The RL-HV2S is engineered for contractors who work across multiple disciplines. Whether you're setting finish grade on a commercial pad, plumbing tilt-up wall forms, checking elevation on a structural steel pour, or laying out interior stud walls, this laser transitions between horizontal and vertical plane operation quickly. The dual-slope capability lets you dial in grade in two axes simultaneously, which is critical for drainage swales, sloped slabs, and ADA-compliant flatwork. The LS-100D receiver extends working range and provides clear audio and digital readout feedback so rod men can work independently without constant radio check-ins.

- Operator manual and quick-start documentation
Job Applications
Grading and Earthwork: Set dual-axis slope across a full site and let machine operators or rod men work at full 2,600 ft range. The LS-100D gives clear cut/fill feedback without the operator returning to the instrument.
Concrete Forming and Flatwork: Use vertical plane mode to plumb forms, set batter boards, and check wall alignment. Switch to horizontal mode for slab elevation and drainage slope layout in minutes.
Steel and Structural Layout: Vertical beam mode makes fast work of column plumb checks and anchor bolt layout on large pours where a plumb bob or transit is impractical.
Interior Finish Work: Drop ceilings, partition framing, and MEP rough-in all benefit from a self-leveling horizontal plane. The compact head mounts on standard tripods and positioning is fast with the auto-level system.

Frequently Asked Questions
- Can the RL-HV2S set slope on both axes at the same time?
- Yes. The RL-HV2S supports simultaneous dual-axis slope up to ±10% on both X and Y, making it one of the most capable instruments in its class for drainage and ADA ramp work.
- What is the difference between this kit and purchasing the laser head alone?
- This 1051612-17 kit includes the LS-100D digital receiver and the Holder 110 rod clamp. Buying the kit saves you the cost and time of sourcing these components separately and ensures full compatibility out of the box.
- Is the LS-100D receiver included compatible with other Topcon lasers?
- The LS-100D is designed for use with Topcon red-beam rotary lasers. It is generally compatible across multiple Topcon models, but always verify compatibility with your specific instrument before mixing components.
- What is the IP rating and can I use this laser in rain?
- The RL-HV2S carries an IP66 rating, meaning it is fully protected against dust ingress and resistant to heavy water jets. It is built for active jobsite conditions including light to moderate rain, though submerging the unit is not recommended.

The 1051612-17 kit includes the LS-100D digital receiver and the Holder 110 rod clamp bundled with the laser head. This saves you time and ensures full component compatibility compared to sourcing the receiver and clamp separately.
Is the LS-100D receiver included compatible with other Topcon lasers?
The LS-100D is designed for Topcon red-beam rotary lasers and is generally cross-compatible with multiple models in the Topcon lineup. Always verify compatibility with your specific instrument before mixing components from different kits.
What is the IP rating and can I use this laser in the rain?
The RL-HV2S is rated IP66, meaning it is fully protected against dust and resistant to heavy water jets. It is designed for active jobsite use in light to moderate rain. Submerging or exposing the unit to sustained water immersion is not recommended.
