The unit has an over-molded housing to ensure dependable operation, strong grip and protection from water and dust. A blinking laser indicates the out-of-level condition. Classes include professionally produced videos taught by practicing craftspeople, and supplementary downloads like quizzes, blueprints, and other materials to help you master the skills.This is Bosch’s two-point plumb lasers projection which accurately transfers points from floor to ceiling by magnetically mounting to metal surfaces. MT Copeland offers video-based online classes that give you a foundation in construction fundamentals with real-world applications. If just one corner or one line of what you’re building isn’t straight, then what you’re doing won’t be true.

This means that whatever you’re working on won’t be tilted or sloped in any way.Įvery element of your orientation must be exact. Your lines should be perfectly vertical (plumb) and horizontal (level), and your corners should be exactly 90 degrees (square).

In construction, “true” is about everything being lined up correctly. This tool helps you measure and mark perfect 90-degree angles, also known as right angles. To ensure that a corner is square, you can use a tool known as a steel square, carpenter square or framing square. Perpendicular lines meet to create a right angle, which is what you should have at every corner. Corners should be at exactly 90 degrees, which means they consist of two perpendicular lines: one straight horizontal (level) line and one straight vertical (plumb) line. You can also use spirit levels to check if something is plumb, as these tools measure both level and plumb. That line will be perfectly perpendicular to the horizon, or “plumb.” With the help of the weight, the string follows the path of gravity and goes straight down from the top of what you’re measuring. This tool consists of a weight (usually with a pointed bottom) that is connected to string (also known as a plumb line ).

How to use a plumb bobĪ plumb bob uses gravity to help you align things properly. You can measure if something is plumb by using a plumb bob or a spirit or laser level. Something that is “plumb” runs perpendicular to the horizon-meaning that when it intersects the horizon, it makes a right (90 degree) angle. “Plumb” is what you call a perfectly vertical line. Laser levels work in all directions, so you can use them to measure level and plumb by pointing at whatever you are checking. If you have to measure multiple lines, a laser level will make things easier than having to place a spirit level on each individual line.

Laser levels use a laser beam of light, to check alignment.

Water levels use plastic tubing and cylinders of water to measure level over longer distances than could be achieved with a simple bubble level.

(More on that below.) Other types of levels Tip: When you are holding a level, make sure it is on or against a flat surface, such a wall or flat straight boards, to ensure accuracy.
