FAQ — Plumbob

What is a Plumbob?

A Plumbob is a pointed weight, usually made of metal, suspended from a string to establish a true vertical reference line used in construction and surveying.

How does a Plumbob work?

When suspended, gravity pulls the plumbob directly downward, aligning the string to a true vertical line, helping ensure structures or surfaces are perfectly upright.

What materials are Plumbobs made from?

They are commonly made from brass, steel, or other durable metals, providing weight and resistance to wind movement for steady alignment.

What sizes are available for Plumbobs?

Standard sizes range from 100 g to 500 g or more, depending on the accuracy required and the working environment.

Where is a Plumbob typically used?

Plumbobs are used in masonry, carpentry, and surveying to align walls, columns, door frames, and structural components accurately.

How do I use a Plumbob correctly?

Attach the plumbob to a non-stretch string, suspend it near the structure, and wait for it to stabilise before marking the vertical alignment point.

What is the difference between a Plumbob and a Spirit Level?

A Plumbob measures vertical alignment using gravity, while a Spirit Level measures both horizontal and vertical levels using liquid vials.
