Spectra Precision Laser GL412 & GL422 Grade Lasers
Contact us about this product
The Spectra Precision® Laser GL412 and GL422 Grade Lasers are cost-effective, automatic self-levelling 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.

• General construction vertical alignment and plumb such as anchor bolt and form alignment
