Install tile with professional results while saving time with QEP LASH Tile Leveling Wedges. These Wedges, Part B of a 2-part system, hold the tile at an even height for lippage-free results, ensuring a consistent finish and correcting tile bowing. The Clips, Part A, produce even grout lines and raise neighboring tile of the same thickness for a level finish (sold separately). For quick and easy removal, the single-use Clips are designed to break off below the surface of the tile with a kick or strike of a floor mallet, while Wedges can be saved and reused. The QEP LASH Clip and Wedge Tile Leveling System is used by professional and DIY installers alike to save time while providing a level and consistently spaced tile. Material: Plastic.
