ABSTRACT:
A level having a frame with an edge rail and a web extending from the edge rail at right angles. A web opening is provided in the web. A capsule assembly is mounted on the web at the web opening. The capsule assembly has a transparent capsule having a liquid therein and outer cover plates mounted over the capsule on each side of the web. The volume of the liquid in the capsule is less then the volume of the interior of the capsule so that an upper surface of the liquid is formed in the entire surface of which is viewable through the transparent capsule.
