Replacement tile and adjustable base roof attachment for rail-based PV racking on S-profile tile roofs. The universal base pairs with an S-tile flashing that provides built-in, deck-level flashing on all four sides and replaces a complete tile for a watertight installation. Two structural attachment points optimize pullout values and eliminate the need to cut or grind tiles. Works with EcoFasten L-foot brackets (ClickFit Universal 3 in or Open Slot 3 in); 25-year warranty.
