Inspection mirrors with a magnet base have a large mirror head, held up by a rigid shaft with two ball joints, allowing them to be bent into different positions. The magnetic base allows the tool to be temporarily fixed to ferromagnetic surfaces.
Mirror head
The mirror heads on inspection mirrors with magnetic bases can be either round or square?
Metal shaft
The metal shaft has two swivel ball joints to allow it to be bent into different positions for the user. They are, however, rigid enough to keep the desired position and hold the mirror there.
Magnet base
The magnet base has a powerful neodymium magnet in a metal casing which attracts to ferromagnetic materials.
