What is a "Plumb Bob?"

Updated: May 14


Have you ever wondered what that symbol between the “m” and the “a” in our “w.e.bowman” logo is? It’s a Plumb Bob! A Plumb Bob uses a weight on a line to measure a perfect vertical line, often utilized in building arches, domes, and other tall structures. Instead of measuring how horizontally “level” something is, one can measure a vertical distance and the string will provide a vertically “plumb” line marking both the desired point on the ground and a point at the other end of the string. The “bob” is often made of steel, brass, or other metals and has been used by ancient builders--such as the Egyptians--for eons. Even though many builders now use laser pointers instead of the Plumb Bob, it is still a tool today readily available at any Lowe’s or Home Depot. We use it in our logo because with a Plumb Bob, one can see what is straight up and what is straight down. And furthermore, this reliable tool does so in a clear and simple manner.
