ABSTRACT:
A combination level has a carrier forming two opposite parallel major surfaces. A tube level is mounted on one of the surfaces of the circular level and a circular is mounted on the other, opposite, surface. either one of the major surfaces can be used directly to abut against a work to be aligned or an additional, preferably elongate, member can be attached to the carrier and which abuts against the work. The carrier is mounted on the abutting member at known angular relationship or the carrier can be mounted for selected angular adjustments abutting to the abutting member, so that selected positioning of the tubular and circular levels are relative to each other on substantially horizontal planes where contact of the work, allows measurement of vertical alignment and plumb condition of the work.
