"Install tile with professional results while saving time with QEP LASH Tile Leveling Clips. Level, Align, Space and Hold tile in place to prevent lippage, ensure a consistent finish and correct tile bowing. The Clips, Part A of a two-part system, produce even grout lines and raise neighboring tile of the same thickness for a level finish. The Wedges, Part B, hold the tile at an even height for lippage-free results (sold separately).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 wall or floor. * 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." *
