ABSTRACT:
A simply-constructed miniature level device in which a small ball bearing, a visual indicator of a level condition of the device, is maintained between two races, that is, arcuate slots formed in opposing panels which are spaced-apart by opposing leg portions extending between the panels. A sleeve member disposed between the panels allows for the level to be supplied with a key-chain or key ring.
