ABSTRACT:
The level of the invention consists of a solid, thin central web that is connected to an upper box and a lower box. The central web supports level vials. The upper box and lower box have a hollow generally polygonal shape and define an upper surface and lower surface. A surface of either or both of the upper and lower boxes are calibrated with respect to the level vials to create leveling surfaces. The level vials are enclosed in housings that secure the level vials to the web. End caps are secured to the ends of the web and the upper and lower boxes.
