RUBI manufactures spacers for joints with a high quality base material and, for this reason, they do not present any type of imperfections or burrs. The spacers for joints of 1, 1.5, 2 and 3 mm are recommended for the installation of ceramic tiles and pavements with minimal joint. The massive structure of the spacers for joints of 1, 1.5, 2 and 3 mm has been designed to provide greater resistance to bending and crushing. These properties make cross joints for joints of 1, 1.5, 2 and 3 mm are highly recommended for coatings with ceramic tiles of large formats.
