Abstract
A corner level apparatus arranged for alignment of structural components at a corner intersection includes intersecting first and second arms, wherein the arms define an acute included angle therebetween, generally at forty-five degrees. A mount projects rearwardly of the junction for securement of a spirit level arranged parallel to a top surface of the first and second arms. A modification of the invention includes support legs telescopingly and adjustably mounted relative to a bottom surface of the arms projecting downwardly therefrom for support of the level structure for use as a gauge and a securement of various structural components at the corner intersection of a dwelling, wherein the apparatus in a further refinement includes chalk lines retractably mounted within each of the arms for alignment of the arms and use of the chalk line as a gauge in structural construction.
