The main function of the RUBI DELTA level system is to avoid lippage during the installation process tiles both on floors and walls. The DELTA level system also prevents the movement of the tiles during the setting of the adhesive and during installation, the number of corrections in the position of the tile itself is reduced. The basic principle of the DELTA level system is that of pressing the highest piece, until matching its position with the adjacent tiles, thus obtaining a substantial improvement of the surface flatness. The level system DELTA of RUBI is a system of wedges and strips, recommended for formats of 30x30 cm or greater and varied thicknesses of up to 12, 15 or 20 mm, depending on the model of flange used. The use of the RUBI DELTA level system is fast, easy and intuitive. Once the installation is complete, the strips are removed by impact (kick or mallet), striking the strips always in the direction of the joint. The DELTA level system wedges can be reused many times. The RUBI DELTA LEVEL SYSTEM pliers are designed to be used both in installation work of horizontal (floor) and vertical (wall) tiles. The main function of the RUBI DELTA  level pliers are to give the wedge the necessary pressure to allow the leveling of the tile; thus obtaining a perfectly flat surface. In the design of all RUBI products, the entire RUBI R & D team, made up of engineers and professionals from various parts of the world, has been vital. The fact of receiving information from many parts of the world offers us the possibility of having a global vision of the business and the needs of professionals in the construction sector, in order to design tools adapted to each market.
