The self cross-line laser DW088KD of DeWalt projects a precise cross line for precise horizontal and vertical alignment, deviations beyond are automatically displayed. Thus, for example, can Sockets and light switches quickly attach to a uniform height or lay cables as a guideline exactly perpendicular. The laser is ideal for all interior work. With the easy positionable magnetic angle can be attached to metal surfaces the laser easy. With its rugged, moisture-proof and fully rubberized housing, the cross-line laser DW088KD for use is also under severe conditions. The detector DE0892 with range up to 50 meters is already included.
