California Tile Hangers were created to provide Sid Dickens Collectors with a safer way to display their Memory Blocks. Tiles hang more secure on CTH than on nails, Ooks, or screws, and the tiles will also stay more level on your wall. Tile Hangers also allow for the tile to be slightly adjusted in height (raised) or shifted side to side, which can be helpful when trying to adjust the spacing within a tile grouping.
