Simplifies level, grade, and vertical alignment setups, the Spectra Precision GL412N Grade Laser delivers reliable and accurate performance in various general construction applications. With a working range of up to 2,600 ft., it has a grade capability of 10% to plus 15% on a single axis. The GL412N is also self-leveling horizontally and vertically within 5° and has an accuracy of 1/16 in. per 100 ft. 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 GL412N grade laser and offers an easy to use menu-driven interface. With a working of up to 330 ft., this radio remote gives the ability to make long-range grade changes and automatic alignments. 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, this laser level is protected against dust and water jets from any angle. It can also withstand drops of up to 3 ft. onto concrete and tripod tip-overs up to 5 ft. This slope laser uses NiMH batteries and works up to 35-hours of continuous use.
