ABSTRACT:
A tool for household, commercial, and industrial use is disclosed. The tool would be a multi-sectional level that would comprise many individual sections that would be pivotally attached to one another, with each section having a cylinder and a volume of liquid in the cylinder. Each cylinder would also have an internal bubble for use in measuring flat surfaces. The level could also be placed in a slide-lock mechanism to force the level into a straight shape. Either one or two slide-lock mechanism could be used with the level.
