Versatile Automatic Grade Lasers for Level, Grade and Vertical Alignment
The Spectra Precision® Laser GL412 and GL422 Grade Lasers are cost-effective, automatic self-leveling lasers that do three jobs - level, grade and vertical alignment with plumb. Both lasers feature a 2-way, full-function remote control so you can make grade changes from anywhere on the jobsite for reduced setup time and faster operation.
The GL412 (single grade) and GL422 (dual grade) lasers send a continuous, self-leveled 360-degree laser reference over your entire work area, and have a wide grade range so they can be used in a variety of slope applications.
