PRODUKTDETAILS
The Mountlaser KRL-540 is a red-beam rotary laser kit with the LP700 digital receiver. Set a horizontal or vertical reference for construction layout and use two-way tilt to work to a planned slope. The included LP700 digital receiver displays the offset from the laser plane for cut-and-fill checks at the grade rod.
Fine elevation checks, vertical layout and two-way slope work
Choose the KRL-540 when the work calls for the tighter leveling specification and you want an LP700 digital receiver.
Start with a level benchmark. For slope work, set the grade described in the red-beam instructions, then confirm both axes against known points before taking production readings.
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-540 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.
