Milwaukee 3522-21 USB Rechargeable Green Cross Line & Plumb Points Laser
4X Brighter Visibility. All-Day Runtime. Zero Downtime Layout.
The Milwaukee 3522-21 is the professional's solution for high-accuracy leveling and alignment. Powered by the REDLITHIUM™ USB platform, this laser delivers over 8 hours of continuous runtime, eliminating the cost and frustration of disposable alkaline batteries. The high-intensity green laser beams provide uncompromised visibility up to 100 feet (165 ft. with detector), ensuring your cross lines and plumb points remain crisp and clear even in brightly lit environments.
For the craftsman at The Fastener Group, the 3522-21 is built for speed. It features an integrated magnetic bracket with micro-control, allowing the laser to pivot on a point for instantaneous point-to-point alignment over long distances. With amplified rare-earth magnets that secure to metal studs and integrated screw/nail hang holes, this laser provides a rock-solid setup in any environment—from residential framing to commercial electrical rough-ins.
Key Features & Professional Benefits:
- High-Intensity Green Laser: 4X brighter than traditional red lasers, providing a visible 100 ft. working range for fast and accurate leveling.
- REDLITHIUM™ USB Rechargeable: Delivers 8+ hours of all-day runtime; charge the battery internally via Micro-USB or swap it for virtually zero downtime.
- Micro-Control – Pivots on Point: A precision adjustment dial that allows for faster set-up and easier alignment without losing your plumb point.
- Plumb Point Access with Riser: Includes a specialized floor mount that raises the laser 2 inches, providing clear access to the bottom plumb point over tracks and plates.
- Amplified Rare Earth Magnets: Provides a secure hold on metal surfaces that won't slide, essential for commercial steel stud framing.
- Locking Pendulum: Protects the internal components and maintains calibration during transport and storage.
- Jobsite Durability: IP54 rated for water and dust resistance and impact-tested up to 1 meter to survive the rigors of the construction site.
