The Stabila LAX 300 Cross Line Laser Level is ideal for marking out floors, walls and ceilings. It has 3 functions and a visible line range of 20m with a red laser diode. Has 3 lines: one horizontal line, one upwards vertical line, and one downwards plumb-line make the laser well suited for the transfer of the layout from floor to roof. The laser also allows quick and precise plumbing. A very bright, narrow and clear laser line is visible up to 20m. The laser can be rotated through 360 in its housing and can be used directly on the floor, attached to a tripod (1/4in thread), fastened to metallic objects by its rare earth magnet and V-groove or secured by the metal lugs using a strap. The laser level has a shock-absorbent STABILA soft-grip casing, providing high protection (class IP 54). There is optimal protection of the optical equipment against dust and scratches by rotation inside the U-shaped housing. Thanks to the pulsed laser lines, the LAX 300 can be used both inside and out.
