Borrow Plumb Line (DIY190)

A plumb line is a tool used to establish a vertical reference line. It consists of a string with a weight (known as a plumb bob) attached to one end. When the weight is allowed to hang freely, it indicates a perfectly vertical line, which is essential in construction and carpentry for ensuring that structures are aligned correctly. Masons and builders commonly use plumb lines to ensure walls are straight and true, aligning with the gravitational pull.
