A laser level is a laser-based tool that enables plumb, level, or square measurements to
be established quickly and accurately. Laser levels are used to set foundation
levels, establish proper drainage slopes, square framing, align plumbing
and electrical lines, and when hanging drop-ceilings. A great advantages
is that they enable one person to do a job that normally takes two. Instead
of one person sighting through the optical scope taking readings while a
second person holds a rod, the laser level is set up, turned on, and the
same person can go around with the stick to take the readings.
A laser may be mounted on a tripod, fastened onto pipes or framing studs,
or suspended from ceiling framing. Levels for professional construction
jobs are housed in sturdy casings designed to withstand jobsite conditions.
These tools come in a variety of sizes and weights depending on the application.
