Self leveling floor tile spacers are tools used during the installation of floor tiles that can adjust the spacing between the tiles. These tools are particularly useful when the surface of the floor is uneven or the size of the tiles varies, as they ensure that each tile is equidistant from its neighbors, regardless of any sloping or unevenness. By using these spacers, tile installation can be faster, more precise, and result in a more aesthetically pleasing finish.
