The 8-in-1 1/16 in. and 3/16 in. Tile Spacers align and space both wall and floor tile. They ensure that your grout lines are the same width. You can switch these spacers around to provide you with either 1/16 in. or 3/16 in. joints, as well as breaking off to switch between cross, brick and flat joints. It also comes with a re-useable box to make sure you don't lose any spacers between jobs.
