Description: This robust cross line laser with its five green, individually switchable laser lines, is suitable for precise alignment of horizontal and vertical surfaces and slopes. The four vertical laser lines have a perpendicular alignment with respect to each other. The device has an upper laser cross and an additional lower plumb laser for a precise plumb function. Pre-adjustment is by a vial and height-adjustable feet. The rotatable housing with vernier adjustment mechanism and a horizontal circle allow the laser lines to be precisely positioned. Optical signals warn the user when the unit is outside its levelling range. Together with an optional hand-held receiver, the integrated hand-held receiver mode allows laser lines to be detected over long distances and under unfavourable light conditions. A pendulum restraint provides excellent protection during transportation.
