ABSTRACT:
A hand tool for leveling operations includes level and plumb indicators in an elongated, linear support member, or body. Disposed on opposed ends of the support member are first and second telescoping extension members. By positioning the distal end of one extension member in a recessed point or line on a wall, commonly known as a "quirk", and using the level indicator, a point or a line on another adjacent wall at the same elevation, or height, may be precisely located. The opposed extensions may also be used with a ruler to precisely measure the vertical distance between a structure inaccessible by a conventional level, such as a doorway header, and the edge of an adjacent structure, such as a ceiling beam. Another embodiment includes a plurality of spaced, retractable projections along the length of the support member which are particularly useful for leveling a structure such as where the level is too long for positioning within the structure, such as a doorway. Two or more of the projections may be positioned in contact with an inner surface of the structure for precisely leveling or plumbing the structure.
