Schluter-KERDI-DRAIN is a floor drain specifically designed to allow connections to Schluter-KERDI or other load-bearing, bonded waterproof membranes, typically in shower applications. Bonded waterproof membranes represent the current state of technology and are increasingly used for ceramic tile and natural stone coverings. Schluter-KERDI is adhered to the drain's large, trapezoid-perforated bonding flange, which is covered with a fleece webbing, to form a waterproof connection at the top of the drain assembly. KERDI-DRAIN features a square, fully adjustable grate to accommodate 1/4" (6 mm) to 1-1/4" (32 mm) tile thicknesses. The grate assembly allows lateral and tilt adjustment as well. KERDI-DRAIN is designed to simply integrate with standard 2" (51 mm) drain pipes, making it suitable for new construction and renovation.
