It is not known who invented the plumb-line or plumb-bob; there is evidence that it has been in use since biblical times and archaeologists haveÊunearthed what they think are plumb gaugingÊtoolsÊin Ancient Egypt.
Use of a plumb bob a level used on plumb rather then horizontal
In a vertical or perpendicular line. e.g. "The wall is plumb."This is the most common meaning and alludes to the method of establishing vertical by using a plumb bob - a weight suspended from a long line which hangs straight down - with the resulting line between the top of the line and the plumb bob being a reference for the edge of something that is supposed to be perfectly vertical. If it is further away from the line at the top or bottom of the line than it is at the other end, it is not quite "plumb".There are, of course, several more informal uses for the term:(Informal definition) Directly; squarely: e.g. "It fell plumb in the middle."(sometimes also spelled as "plum" with the informal definition...) Utterly; completely: e.g "I'm plumb worn out."informal chiefly US (intensifier): e.g. "That's just plumb stupid."
Plumb as in "Plumb a door frame or cabinet?" Plumb is having something 90 degrees to level. The floor is level and the door frame, the vertical, up and down part is plumb in relationship to that. I'm sure this term comes from using a Plumb Bob. That's a heavy pointed ball on a string.. It will always show you the plumb line. Haven't heard the term used in plumbing.

Plumb line testThis is a quick visual check to see if the spine is straight. In scoliosis, the plumb line will fall to the left or right of the spine instead of through the middle of the buttocks. Plumb line dropped from the prominent vertebra of C7 (vertebra prominence) measures the decompensation of the thorax over the pelvis. The distance from the vertical plumb line to the gluteal cleft is measured in centimeter and is recorded along with the direction of deviation. If there is cervical or cervico-thoracic curve, the plumb should fall from the occipital protuberance (inion).
A plumb-line can be made of steel, metal, gold or wood
The plumb line is a vertical straight line.
Compare it to a very fine plumb line. Construct your line with a Peaucellier-Lipkin Linkage (see link below). Examine the line with a laser device.
The spelling for the word describing something that is vertically straight is "plumb."
