Rubi Cyclone Leveling System Caps Rubi's new leveling system is designed to avoid lippage during the laying of ceramic tile in both floor and wall tiles. Rubi has changed the color of the caps from red to grey. The 300-piece caps will be grey, and the other sizes will be grey when stock runs out. The main benefit of making the caps grey is preventing them from leaving marks on white/explicit materials during installation. Besides that, it's the same plastic and has the same properties.
