ADJUSTABLE SPIRIT LEVEL FOR TILE AND CABINET INSTALLATION
A spirit level for the installation of tile and cabinets includes a rigid body (14) having upper and lower parallel planar surfaces (18, 22) separated by a first predetermined width (46). The body includes a bubble vial (70) oriented to verify the orientation of the level. An auxiliary edge portion (50) has a planar top surface (54) and lower supporting edges (58) parallel to the top surface separated by a second predetermined width (62). The auxiliary edge portion is removably attachable to the upper planar surface o the body, providing a level having two standard widths corresponding to industry standard tiles. An adjusting notch (154) provided with a recessed planar surface (158) is disposed at either end of the body at the planar lower surface. A bolt (186) engages a threaded opening (206) in the recessed planar surface and extends outwardly to a point beyond the planar lower surface when unscrewed from the opening so as to adjust the level to uneven surfaces (194).
