In practical building construction works, based on its highly straight and fine line indication, it is becoming a major trend for building constructors to operate a 650nm red line laser module. Only after easy connects with 5V, 9V 1000mA DC power supply, this glass coated lens made laser device makes constant red laser beam and red reference line projection. It also enables freely adjusted laser line fineness and line emitting direction within three dimensions, thus it brings users highly straight line indication for all building construction works effectively.

In interior decoration, red laser line generator is used for laying floor and wall tiles, providing a straight red reference line to ensure that the tiles are neatly arranged. When installing doors and windows, red laser line can locate the installation position of doors and windows to ensure that the doors and windows are installed horizontally and vertically. In the construction of ceilings, 650nm red laser line marks the installation position of the keel to ensure the spacing and straightness of the keel installation.
