Abstract:
A measuring and aligning tool for a wall surface, comprising in combination:a single elongated body having a non planar shaped configuration, the elongated body having a flat rear wall spaced apart from a raised front wall enclosing a continuous uniform sized hollow space therebetween, the flat rear wall and the outer raised wall and the hollow space having a uniform cross-sectional shape inside the single elongated body; calibration indicia along at least one side of the elongated body; first slider for sliding along and around the elongated body, and having a flat rear wall which slides against the flat rear wall of the elongated body, the flat rear wall of the first slider adapted to be abutted against the wall surface, the flat rear wall of the first slider having a raised flat flange portion which extends upward and has an opening for allowing a mark to be formed therethrough on the wall surface; first indication means for indicating a level condition on the first slider; second slider for sliding along and around the elongated body, and having a flat rear wall which slides against the flat rear wall of the elongated body, the flat rear wall of the second slider adapted to be abutted against the wall surface, the flat rear wall of the first slider having a raised flat flange portion which extends upward and has an opening for allowing another mark to be formed therethrough on the wall surface; wherein each of the first and the second sliders has a switch-lock cam having two depressible leave portions on opposite sides of a mid-portion for pivoting between and on opposition where each of the sliders is locked in place on the elongated body, and an off position where each of the sliders is freely slidable along the elongated body and second indication means for indicating a level condition on the second slider, wherein positioning the first slider and the second slider spaced apart from on another aids in aligning an object to be mounted on a wall.
