Preventing "Lippage":** They hold the tiles at the same height relative to each other while the mortar or thin-set cures. This eliminates "lippage"—the uneven edges that happen when one tile sits slightly higher than the one next to it.
* **Maintaining Consistent Grout Lines:** The clips act as spacers, ensuring a uniform 3.0mm gap between your tiles.
* **Speed and Accuracy:** They help both DIYers and professionals achieve a professional, smooth finish much faster than using traditional methods, especially when working with large-format tiles.
