Complex levelling made simple – the easy-to-use cross line laser GLL 3-50 Professional is designed for versatility across all standard levelling and transfer applications. The two vertical laser lines, a single horizontal laser line, and the plumb dot make it easy to tackle an impressive range of jobs. Compactly designed, the GLL 3-50 Professional offers comfortable handling and control. For convenient laser line positioning, it comes with a rotating mini-tripod with height-adjustable feet and fine adjustment of the vertical line.
It is suitable for various interior applications such as mounting shelves or windows, as well as installing drainage pipes or wall tiles. A second vertical laser line also makes it ideal for quick squaring.
The GLL 3-50 Professional offers laser lines with up to 10 m working range that can be extended up to 50 m by using the optional LR 2 Professional laser receiver. The plumb dot range is up to 5 m. This cross line laser self-levels in less than 4 seconds. It is robust with IP54 dust and splash water protection.
