Perfect Level Master - Tile Leveling System
The T-Lock™ Tile Leveling System ensures that your tile installation will be leveled on the point tile to tile (each tile is leveled by all tiles around it). It also prevents tiles from warping as your thin-set cures. Lay tiles straight and even on both floors and walls.
Sizes Available For Clips: 1mm (1/32"), 2mm (1/16")
