PRODUCT DESCRIPTION
The Milwaukee 3704-21T M18 Red Exterior Dual Slope Rotary Laser Level Kit delivers precise grade control for excavation, site preparation, concrete work, utility installation, road construction, and large-scale leveling applications. Designed for professional contractors, this cordless rotary laser provides accurate horizontal and dual-slope measurements with a working range of up to 4,000 feet when used with the included receiver. Whether you’re establishing grades, checking elevations, aligning forms, or laying underground utilities, the 3704-21T helps crews work faster with reliable, repeatable accuracy across large jobsites.
Built to withstand demanding construction environments, the reinforced housing survives drops up to 1.5 metres and tripod tip-overs up to 2 metres while the IP66-rated design resists dust and water. The included remote control mirrors the laser’s display, allowing slope adjustments from a distance to reduce setup time and improve one-person operation. Automatic Grade Match, strobe light protection, and ONE-KEY compatibility further enhance productivity by simplifying layout work, reducing interference, and helping contractors manage equipment across multiple jobsites.
