The GLL 20-22 G Professional is a robust and intuitive line laser made for a wide variety of applications. With an IP65 rating and rubber-enforced housing, it is made to withstand dust and water, so you can work with confidence in even the toughest conditions. The U-shaped laser window provides a broader fan angle for the horizontal line. And with a dual power source, you can switch between the BA 3.7V 3.0Ah XL Li-Ion battery and AA alkaline batteries - helping to eliminate downtime and increase productivity.
The BA 3.7V 3.0Ah XL can recharge while in use and ensures that your work flows seamlessly, without power interruptions. The GLL 20-22 G is ideal for staircase construction, aligning walls, sockets and partitions, and tile and flooring installations.
The tool features a large battery indicator for easy readout. The bright green laser lines provide up to four times better visibility than red lines to make your levelling easier – no matter where the job takes you.
