Product Description

GL422

*5 Year No Cost Warranty*

The Spectra Precision® GL422 (dual grade) Laser is a cost effective, automatic self-leveling laser that does three jobs—level, grade and vertical alignment with plumb. The GL422 features a 2-way, full function remote control with a built-in back-lit grade display. You can do everything with the remote control that you can do at the laser keypad, including grade reverse on both axis, up to 330 ft away from the laser—even from the cab of the machine! The ability to make grade changes from anywhere on the job greatly reduces setup time and speeds operation, especially when multiple job grade breaks are needed.

Additionally, the GL422 Grade Laser self-plumbs in the vertical position, to allow an even wider range of applications such as anchor bolt installation, plus form, tilt up and curtain wall plumbing. This unit also incorporates automatic temperature and grade compensation for high accuracy in any weather or geographical location. The laser beam can be turned off electronically on up to 3 sides of your choice In Mask Mode. This capability eliminates interference with other crews on the job site by keeping the beam from straying into other work areas.

The GL422 offers two additional advanced features: pointing mode for “Over the Top” pipe laying applications and grade match where the laser can be used to measure the existing grade value between two known elevation points.

Use this versatile laser with a Spectra Precision Laser HL700 Laserometer at an operating diameter up to 2,600 ft.
