They are available in Cross, Linear (straight) and ‘T’ shapes with spacer widths of 1 mm, 2 mm, 3 mm and 5 mm. The base of each Leveler has four holes for anchoring between the mortar and tile. The vertical legs of the Leveler rise from the base and act to space the tile. The legs are ‘coded’ for their millimeter width by the number of holes in one leg.
