A high-quality German plumb line designed for making vertical lines or determining the location of a suspension point in relation to a lower level. This allows, for example, to align ceiling joists or structures directly to floor structures or to ensure that vertical structures are straight.

The plumb bob is suspended from either the ceiling or other similar overhead structure. Thanks to the heavy weight of the plumb bob, the plumb bob creates a perfect straight line towards the ground using the effect of gravity.

The package does not include thread.
