![]() When measuring a window, plumb refers to the vertical planes, and level refers to the horizontal planes. You achieve this by obtaining correct measurements. When putting in new windows, it is important to ensure they are weather tight. Plumb and level are two important terms for anyone doing window installation. If the bubble is off center, then your surface will be rising up to the side that the bubble is higher on. ![]() If the bubble is centered, the surface you are checking is level. The bubble in the center of every vial (if there is more than one) should be centered between the two level indication line marks. A plumb was used to establish vertical points that were crucial in the construction of Egypt’s buildings, pyramids and canals. It has two unassuming parts-a string and a weight. Then pull it and let it go, snapping it against the wall.Įgyptians invented the plumb bob more than 4000 years ago. Holding the bob where it falls naturally, pull the cord taut. Then attach a plumb bob (or other small weight) to the loose end. To make a plumb line, rub a string with colored chalk and tack it to the top of the wall. When something is “level,” it’s straight from side to side, like a shelf that’s been properly installed. What is a plumb wall?Ī structure is often called “plumb,” meaning it is straight up and down, like the walls of a building. Plumb is vertical, most accurately gauged by a plumb bob. Level is always gauged by a device, such as a carpenter’s level, but level does not always mean parallel to the ground. Square means that corners are 90 degrees. What’s the difference between square and plumb? Excavation and foundation contractors rely upon the plumb line, and constructing a chimney the tool can indicate whether a flue is running true vertical or veering off plumb. Surveyors sometimes use plumb bobs for lining up points or transferring them. What is plumb level?ĭefinition of plumb level : a level with a plumbing attachment (as a horizontal arm and a plumb line at right angles to the arm) Who uses a plumb line? 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 comes from the Latin plumbum, or “lead,” the material that replaced stone as… What is a plumbline in construction?Ī plumb line is a piece of string with a weight attached to the end that is used to check that something such as a wall is vertical or that it slopes at the correct angle. Why is it called a plumb line?Ī plumb line is a light line with a weight (plumb bob) at one end that, when suspended next to a workpiece, defines a vertical line. The tool is also used in surveying, allowing the user to find nadir (the local vertical direction pointing towards gravity), and in tools such as steel tape and theodolites. ![]() Plumb bob has been around for thousands of years, dating back to Ancient Egypt. Plumb is the vertical equivalent to a spirit level. Why is making sure things are plumb and square important?.What is the difference between host level and plumb bob?.What tool is used for vertical alignment?. ![]()
