Size of a Plumb-Bob
The plumb bob dimensions are often specified by the weight in ounces. 
The weight can be anywhere from 4 ounces to over 16 ounces. In terms of the physical size, 1 x 4 x 8.7 niches (L x W x H), 2 x 6 x 6 and 2 x 4 x 7 are quite common.
Plumb Bob Information
The plumb bob is a piece of metal used to weigh down a piece of string hooked to it. This is to denote plumb, a precise vertical setting. The tool is very old, dating back to the ancient Egyptians.
In fact, some researchers believe that the plumb bob was used by the Egyptians to set the pyramids’ vertical lines. Today however, it is considered a fundamental toolbox item by modern workers.
Design and Features
The plumb bob dimensions differ and so are the designs. The most basic plumb bob consists of a string with a small metal hooked to it. The metal acts as the weight. More intricate plumb holes will have metal or wooden parts.
There are also some plumb bobs with 24k gold tips. These parts may also have various ornamental designs included. There are also some plumb bobs today marketed as kits. These can be found in woodworking shops and stores.
Fancy plumb bobs have numerous sections but the basic ones are often designed as a single piece. The unit will just have a string connected to it. The basic plumb bob are constructed in a basic geometric shape.
The head is often metal, consisting of steel, lead or brass. The shape is usually triangular and smooth. The head can also be comprised of plastic. The end or tip is sharp. The end is indicative of the straight or plumb direction required.
How the Plumb Bob Works
Gravitational force causes the plumb bob string to go down flat. This helps denote the plumb vertical line. As stated earlier, the plumb hole weights vary.
When the plumb bob is set on a nail by the string, it will show the vertical line precisely. You can make the line appear at the wall by putting some chalk on the string. In some cases this will be really handy.
When checking the plumb bob dimensions, start by looking at the weights. After deciding on what you need, you can check out the physical dimensions of the product and the length of the string.
