  • Patent number: 7497022
    Abstract: An infinitely adjustable level with a least one extender that extends outward from the end of a central body. The level indicating devices can be attached to the extenders, to the central body, or to the extenders and the central body. In this manner the level indicating devices will never be obscured as the extenders are adjusted, no matter what the length of adjustment might be. The infinitely adjustable level provides a method of positioning a level indicating device in a manner such that the level indicating device can be moved to a location for best and most accurate viewing by the operator. The infinitely adjustable level provides a method of locking the central body with the extenders so that relative lateral movement is eliminated.
