The tool-less self-leveling Vision system provides a perfectly flat and level tiling surface. Eliminate any level shift between tiles. It prevents movement of the tiles during gluing and during the curing of the glue. Significant time saving, guaranteed result. Tile leveling system is used in glued installation for tiles 5 to 15 m thick. The braces are placed under the tiling. Apply the glue, place the braces under the tiles. Screw the translucent pommels and place them in their final place by tightening them on the spider. Remove any visible parts once everything is dry. Infinitely reusable knobs also for structured tiles. Use X cross braces at the corners of the tiles, T cross braces for herringbone and offset tiles
