Product Overview & Jobsite Applications

The GL622N-19 builds on Spectra Precision's GL622N platform by bundling it with an elevator tripod that provides smooth, tool-free vertical adjustment from approximately 4 to 7 feet. The laser head can be repositioned up or down along the elevator column while retaining grade settings, eliminating the need to re-establish slope references when changing work heights. This makes the GL622N-19 particularly effective on sites where crews are transitioning between subgrade, base course, and finish grade elevations throughout the day. The dual grade system controls X and Y axis slopes independently, with digital readouts allowing precise tenth-of-a-foot elevation inputs for elevation control workflows.

Job Applications

Terraced Site Grading: Contractors grading multi-bench sites can reposition the laser head vertically between bench levels without resetting grade angles, keeping crews moving efficiently between elevation changes.

Concrete Flatwork & Slab Pours: The dual axis grade control supports precise slope-to-drain layouts on parking structures, warehouse floors, and sloped concrete flatwork where both X and Y pitch must be independently dialed in.

Drainage & Pipeline Installation: Elevator height flexibility lets crews position the beam at optimal receiver height in trenches while maintaining exact fall-per-foot settings across long drainage runs.

Multi-Story Construction Layout: The elevator tripod's extended height range supports floor-to-floor layout work where the laser must be raised to clear formwork or reference higher structural elements.

Frequently Asked Questions

Can I adjust the elevator tripod height without losing my grade settings?

Yes. The elevator tripod column allows vertical repositioning of the laser head independently of the grade control system. Your X and Y axis slope settings remain locked in as you raise or lower the head along the column.

What receiver is recommended for use with the GL622N-19?

Spectra Precision recommends the HL760 laser receiver for use with the GL622N series. It provides a large detection zone and digital grade readout, making it ideal for machine control and rod work at the ranges this laser supports.

Is the GL622N-19 suitable for machine control applications?

The GL622N is compatible with grade control systems when paired with a compatible machine-mounted receiver. However, for dedicated machine control workflows, verify receiver and system compatibility with your grading equipment manufacturer before purchase.

What is the warranty on the Spectra Precision GL622N-19?

Spectra Precision backs the GL622N with a standard manufacturer's warranty covering defects in materials and workmanship. Contact Express Tools or refer to the documentation included with your unit for full warranty terms and service center information.
