LASH360 Tile Leveling Round Caps are Part A of QEP's LASH360 Tile Leveling System. Used with Part B, the stems, these round caps hold the tile at an even height for lippage-free results, and are designed to provide convenient visibility of a set of joints at a time. They are ideal to install porcelain, ceramic and all natural stone tile up to 3/4 in. thick, and can be removed after installation and reused.
