The Hilti PM 4-M multi-line laser lets you position and align objects such as cable trays, pipes, suspended ceilings or doors and windows quickly and with millimeter accuracy. Thanks to a new design, the reference point is projected directly below this laser tool. The shape of the tool allows it to be rotated without constraint around this reference without risk of incorrect positioning or alignment caused by shifting lines. The three laser lines projected by the Hilti PM 4-M can be activated individually and, in conjunction with a laser receiver, have a range of up to 50 m.
