PRODUKTDETAILS
The Mountlaser KRL-420 is a red-beam rotary laser kit with the LP700 digital receiver. Use the rotating horizontal plane to transfer elevations, then switch to a vertical reference for alignment work. The included LP700 displays the offset from the reference plane, so you can read how far the detector is above or below grade.
Horizontal and vertical layout with a digital receiver
Choose the KRL-420 when one instrument needs to cover both elevation transfer and vertical alignment, and you want a digital readout at the rod.
For elevation work, level the instrument and set the LP700 to the benchmark. For vertical layout, set the unit in the operating orientation specified by the red-beam manual and align the reference before marking.
Receiver included with this kit
The LP700 digital display shows the offset from the laser plane. The receiver also has a magnetic top and a clamp for mounting on a grade rod. See the LP700 receiver details.

Frequently asked questions
Is this the red or green version?
This listing is for the red-beam KRL-420 kit with the LP700 receiver.
What does working diameter mean?
It is the full span across the work area with the laser near the center. An 800 m diameter corresponds to a 400 m radius under the rated conditions. Site conditions and setup affect the usable range.
How should I set up the receiver?
Clamp it to a grade rod, face its detection window toward the laser and move it until it indicates on-grade. Set the benchmark before comparing readings elsewhere.
