Levels with magnetic holder

Magnetic holder

— a variation of the holders described above, equipped with a permanent magnet. This design has at least two advantages over the traditional one without a magnet. First, it provides additional security when mounted on a steel surface or other magnetic material. Secondly, many devices with such holders can be placed not only on horizontal surfaces, but also on inclined and vertical ones, as well as upside down on the ceiling - of course, provided that these surfaces are made of a suitable material.
