ABSTRACT:
An infinitely adjustable level with a pair of extenders that extend out from opposite ends of a central body. The level vials can be attached to the extenders, to the central body, or to the extenders and the central body. In this manner the level vials will never be obscured as the extenders are adjusted, no matter what the length of adjustment might be. Also, this form of adjustment allows the level to be used where both ends must butt against objects and there is no way the level can overhang.
