Topcon RL-SV1S Single Grade Rotary Laser Level DB Kit
The Topcon RL-SV1S rotary laser delivers consistent grade control for concrete finishing, drainage layout, and general site elevation work. This DB kit pairs the laser unit with an LS-80L receiver and alkaline battery system, enabling crews to manage single-slope applications across large areas without optical sighting constraints.
- Self-leveling technology maintains accuracy within 1/8 inch per 100 feet
- Single grade slope mode for typical drainage and pad applications
- LS-80L receiver with visible and audible feedback
- Alkaline battery system for crews prioritizing battery replacement simplicity
- 360-degree laser coverage for perimeter grade verification
- IP66 dust and water rating
Concrete contractors, earthwork crews, and general builders use the RL-SV1S for parking lot finishing, foundation elevation control, and site grading. The single-slope design keeps setup fast—positioning the laser unit and following the receiver signal eliminates the complexity of dual-slope configuration. Field teams value the visible beam in moderate indoor light and the audible tone for outdoor work where visual focus shifts between the receiver and forming.
