ABSTRACT:
A level apparatus for spanning two spaced apart building structure points and indicating whether the points are level relative to each other includes an elongate tubular segment having a tubular segment longitudinal abutment face for abutting a building structure point; an extension segment slidably retained within the tubular segment for slidingly extending partly out of the tubular segment and having an extension segment longitudinal abutment face for functionally extending the tubular segment longitudinal abutment face when the extension segment is extended; and a longitudinally oriented bubble site glass. A method of testing whether first and second spaced apart points on a building structure are level relative to each other, using the above-described apparatus, includes the steps of pulling the extension segment outward from the tubular segment; placing the tubular segment against the first building structure point and the extension segment against the second building structure point; and observing the position of the bubble in the site glass to determine whether the first and second building structure points are level relative to each other.
