Plumb Bobs

Since immemorial times, a plummet or plumb bob has been a simple but crucial tool used in construction works for getting vertical reference lines. Typically, it consists of a weight attached to a string, and its role is essential for both aesthetic and static reasons. A straight wall, in fact, is not only beautiful to look at but also statically safe. On the contrary, a leaning wall is disturbing and generates bending and torsion stresses that undermine its stability. Another frequent use of the plummet is to match ceiling and floor points to ensure the perfect alignment of drywall or other panels.

The object at one end of the string can have different weights and shapes to suit various applications. The most frequent design consists of a cone or bullet-shaped piece of brass or steel with a sharp tip allowing workers to highlight the key marks. Weights ranging from 5 to 32 oz work well for typical construction use. Lighter or heavier plummets are suitable for precision or particularly big construction works, respectively. We offer a wide choice of quality plumb bobs and related components such as lines and tips for the most common applications.
