The Spectra Precision GL422N Dual Grade Laser was designed for a wide range of general construction, site preparation, and excavations. This ruggedized, automatic slope laser provides contractors with accurate leveling, grade, and vertical alignment. With a working range of up to 2,600 feet, it has a grade capability of –10 to +15 percent on both axes. The GL422N is also self-leveling horizontally and vertically within ±5 degrees and has an accuracy of ±1/16 inch per 100 feet. For anchor bolt and form alignment, it self-plumbs in the vertical position and can be mounted on a 5/8-11 tripod thread vertically or horizontally.

The Spectra RC402N full-function remote control comes standard with the GL422N grade laser and offers an easy to use menu-driven interface. With a working of up to 330 feet, this radio remote gives the ability to make long-range grade changes and automatic alignments. The Spectra GL422N has an out of level alert that shuts off the grade laser if it is knocked out of place to prevent inaccurate readings. It also has a selection of sensitivity for accurate results even in high winds or on high vibration job sites.

With an IP66 rating, this laser level is dustproof and can be used in heavy rain. It can also withstand drops of up to three feet onto concrete and tripod tip-overs up to five feet. This slope laser uses NiMH batteries and works up to 35 hours of continuous use.

Configuration Options

GL422N: With HL760 Laser Receiver
The Spectra HL760 with digital readout of elevation is a highly versatile laser receiver for basic and advanced leveling and aligning applications. With a unique fingerprint function, it is easily paired with the GL422N to detect only its laser beam and avoid conflict between other laser levels working in close proximity. This laser receiver also provides automatic grade matching and PlaneLok to eliminate manual slope adjustments and errors due to improper calibration or weather.

GL422N-14: With CR600 Laser Receiver and C51 Magnetic Clamp
Can either be rod or machine mounted, the Spectra CR600 is ideal for a wide range of applications, such as measuring cut and fill, leveling forms and footers, setting grade and measuring elevation changes. This laser receiver can also be used for machine control with the magnetic mount for use on a backhoe, small excavator, box blade or skid steer loader.
