Laser line
A laser line or line laser is an increasingly common construction tool that functions in the same way as a plumb line, chalk line or spirit level, to indicate a level line across a building element or site.
It is a small device, similar to a laser pointer that holds a laser and lens, which projects a line (or two crossed lines) of light against a surface. The device usually has a swing, hanger or level to ensure that the line remains horizontal ( with the crossed line perpendicular to this) even if placed on an uneven surface. The laser light is often red or green.
This is then used to find a level point across building surfaces, which might be needed in both structural elements such as the laying of foundations, or in finishing tasks such as tiling, to ensure the tiles remain horizontal. The laser line may also be installed with a clamp or tripod to allow the level to be move up or down as work progresses.
Rotating laser levels will project a level line around all surrounding surfaces.
