Overview for the Spectra Precision GL422N Grade Laser With Vertical Alignment
The Spectra Precision GL422N Dual Grade Laser was designed for a wide range of general construction, site preparation, and excavations. This rugged, automatic slope laser provides contractors with accurate levelling, 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-levelling 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 optional 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 dust-proof 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.
GL422N Grade Laser Kit Components:
- GL422N: With HL760 Receiver & RC402N Remote Control
The Spectra HL760 with digital readout of elevation is a highly versatile laser receiver for basic and advanced levelling 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.
|No Cost 5-Year Warranty offers no repair charge for parts and labor of the laser.
|Shock Proof ensures this construction laser withstands a three feet drop onto concrete.
|Included Radio Remote control is easier to use because it does not have to be aimed at the laser for it to work. This increases the flexibility of the laser for long-range setups while maintaining outstanding accuracy.
|Fingerprint function filters out other lasers that strike the receiver and only accepts the laser that it is paired with.
|Grade Match enables contractors to measure an unknown grade value automatically between two elevation points.
|Dual Axis PlaneLok keeps the laser beam fixed to a receiver in a set position, making it accurate and error free.
Versatile Automatic Grade Lasers for Level, Grade and Vertical Alignment
The Spectra Precision GL422N Grade Laser is a 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 job-site for reduced setup time and faster operation. The GL422 Grade Laser (dual grade) laser send a continuous, self-levelled 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.
Feature & Benefits
- Fast, easy horizontal level, grade and vertical plumb setup with no manual leveling
- Easy setups with the 2-way, full-function radio remote control and single and dual grade application capability offer quick payback
- Automatic temperature and grade compensation eliminates rework
- Very long operating range of 800 m (2,600 ft) for GL422 increases machine control capability and reduces setups over the job site
