These spacers are known for setting straight grout lines. Each intersection is perfectly lined up every time by simply packing the tile tight against the spacer. A major benefit of The TAVY Tile Spacer is that it is extremely easy to remove. The circular design prevents the spacer from bottoming out into the cement or adhesive. Another benefit is the spacer is that it allows the installer to use both sides of the spacer. The cross side can be used at any four corner intersection and the straight edge side can be used at any locattion a spacer is required.
