What is a Plumb bob?

A plumb bob is a tool used in construction and surveying to measure vertical alignment accurately. It consists of a weight attached to a string, which helps determine the exact vertical position by gravity. It is commonly used to check the verticality of buildings or ensure a vertical reference in various construction tasks. The plumb bob's high precision makes it a fundamental tool for ensuring that surfaces or structures are perfectly aligned vertically. The length of the string can be adjusted to suit the specific needs of the task at hand, ensuring correct positioning.
