PRODUCT DESCRIPTION
The Milwaukee 3704-21 M18 Red Exterior Dual Slope Rotary Laser Level Kit delivers accurate grade control for excavation, site preparation, road construction, concrete work, utility installation, and large-scale layout applications. Designed for professional contractors, this cordless dual-slope rotary laser provides precise horizontal and vertical grade control with a working range of up to 4,000 feet when paired with the included receiver. Whether you’re establishing elevations, aligning forms, laying utilities, or checking grades across large jobsites, the 3704-21 helps crews work more accurately while reducing setup time.
Engineered for demanding construction environments, the reinforced housing withstands drops up to 1.5 metres and tripod tip-overs up to 2 metres, while the IP66-rated design protects against dust and water. The included remote control mirrors the laser’s display, allowing convenient slope adjustments from a distance for efficient one-person operation. Automatic Grade Match, strobe light protection, and ONE-KEY compatibility help improve productivity, reduce laser interference, and simplify tool tracking across multiple projects. Compatible with the entire M18 battery platform, this kit delivers dependable cordless performance on every jobsite.
