ABSTRACT:
The invention is a level checking device having a pair of orthogonal surfaces which are positioned precisely as horizontal or vertical references, respectively. The device includes a mounting bracket which is used to mount the horizontal and vertical reference surfaces to a solid support. An adjustment is provided such that, with the mounting bracket appropriately mounted, the horizontal and vertical reference surfaces can be adjusted to be precisely horizontal and vertical. An indicator is also provided to indicate when the precise alignment has been achieved.
