The Tile Leveling System was created to prevent expensive errors caused by uneven tiles that result in lippage during high-end installations. It's an ideal choice for tile planks and large-format rectified porcelain, marble, and stone, and its flat base design is perfect for wall tile installations. This efficient system helps to level tiles and securely holds their edges in place during the curing process. It's the most economical method available to eliminate lippage. The Tile Leveling System is available in four clip sizes: 1/32", 1/16", 1/8", and 3/16", allowing for narrow grout lines with tiles up to 1/2" thick.
