plumbline

Weighted string tool

A plumbline is a cord with a weight attached, used to establish a true vertical.

Builders and surveyors hang it freely, letting gravity do the work—the weighted end points straight down.

Figuratively, a plumbline is any standard for measuring alignment or integrity: The Constitution serves as a plumbline for judicial decisions.

Also spelled plumb line.
