Product Description

Overview for Spectra Precision GL412N-BCC GL412N Grade Laser With Vertical Alignment

Simplifies level, grade, and vertical alignment setups, the Spectra Precision GL412N Single Grade Laser delivers reliable and accurate performance in various general construction applications. With a working range of up to 2,600 feet, it has a grade capability of 10 to +15 percent on a single axis. The GL412N 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, itself-plumbs in the vertical position and can be mounted on a 5/8-11 tripod thread vertically or horizontally.

The Spectra GL412N has an out-of-level alert that shuts off the grade laser if it is knocked out of place to avoid erroneous 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, the GL412N laser level is protected against dust and water jets from any angle. 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

The optional Spectra CR700 laser receiver can be rod or machine mounted, making it ideal for measuring cut and fill, leveling forms and footers, setting grade, and measuring elevation changes. With the magnetic mount, it can be easily attached to a backhoe, small excavator, box blade, or skid steer loader.


Works with the Spectra GL412N in automatic Grade Match and PlaneLok, the optional HL760 laser receiver features a digital readout of elevation and an anti-strobe sensor to prevent false reading from job site strobe lights. It also has a unique fingerprint function that detects only the laser beam of the paired device.


The optional Spectra RC402N full-function remote control offers an easy to use menu-driven interface. With a working range of up to 330 feet, this radio remote provides the ability to make long-range grade changes and automatic alignments. Please select your preference from the menu above.

No Cost 5-Year Warranty offers no repair charge for parts and labor of the laser.
Shock Proof ensures this construction laser withstands 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 accept 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.
