By emitting horizontal and vertical laser lines and two centered plumb points the multifunction laser helps you complete leveling work quickly. The plumb points ensure easy and comfortable carrying. Positioning laser lines around plumb points is easy with the rm 1 professional swivel mount.the gcl 2-15 professional is designed for a variety of jobs such as installing shelves windows and drainpipes and laying flooring. It also allows you to transfer points when positioning lighting fixtures.the gcl 2-15 professional offers a working range of up to 15 m and automatic leveling in under 4 seconds. The multi-function laser works best when combined with the rm 1 professional mount (optional) which is easy to install thanks to a simple sliding mechanism. The tool is durable thanks to its dust and splash protection (ip54 protection). When the tool is switched off the pendulum mechanism is locked allowing for safe transport.horizontal and vertical laser lines are ideal for leveling work over short distancesprecise carrying applications thanks to centered plumb pointsthe rm 1 professional's rotating handle allows for easy positioning of the laser lines around plumb points**illustrative image$
