Abstract
An apparatus and method for securing and aligning level indicators such as bubble vials includes the use of a spring structure with a screw adjuster. In some embodiments, multiple spring structures are positioned perpendicular to one another to allow precise adjustment in different planes. The spring structure is economical to manufacture, and allows accurate adjustment of levels placed in equipment having imprecisely bored holes.
