Abstract
A device and apparatus for aligning exterior faces of tiles of irregular thickness in which elongated alignment grooves are formed in edges of the tiles spaced apart from the exterior faces by a constant setback distance and a front tongue of a spacer shaped like an extruded cross is inserted into the groove in a first tile and then the corresponding groove in a second tile is mounted over the projecting rear tongue. The upper and lower tabs of the spacer define the separation between adjacent tiles and the front and rear tongues maintain the exterior faces of the tiles in alignment.
