The Johnson Acculine Cross-Line Laser Level 40-6640 is an interior construction laser that projects a highly visible green cross beam up to 200 feet and is accurate within ±1/8 inch at 35 feet. Use it to install partitions, lay tile, set pipelines, and many other projects.
Green Cross-Line Beam
The Johnson cross beam laser level projects one horizontal and one vertical line simultaneously, creating a cross beam. Its green lasers are extra bright, making them highly visible. It rotates a full 360-degree, allowing easier measurements in any direction.
This green beam laser levels itself accurately within ±5 degrees. If the unit is tilted beyond the automatic leveling range, an alarm sounds and the laser beams flash. To measure at extreme angles, the self-leveling feature can be disabled and you can tilt it without the out-of-level alarm being triggered. Its automatic leveling pendulum can be locked securely for transport and storage.
This Johnson line laser level includes a magnetic multifunctional mount that enables attachment of the level to walls or metal surfaces. In addition to the integrated 1/4-20 and 5/8-11-inch threads on the laser itself, the multifunctional mount also features both thread sizes so it can be attached to a variety of tripods.
Power and Maintenance
The Johnson line laser level includes a Ni-MH rechargeable battery pack and 6V adapter. It provides up to 20 hours of continuous use with an LED that indicates its power status, is dust and water-resistant, and comes with a 3 year limited warranty.
