• Easily Converts Clamping Ring Drains - The Schluter-Kerdi-Drain-A Adaptor Kit allows for seamless conversion of existing clamping ring drains by adding an integrated bonding flange, ideal when the original drain cannot be removed. • Universal Compatibility - Includes a steel adaptor ring with an over-molded rubber gasket and multiple perforated hole patterns to align with most standard clamping ring shower drains. • Secure, Watertight Seal - The adaptor ring attaches directly to the drain body using existing clamping ring bolts, creating a watertight connection with the included rubber gasket and Kerdi-Fix adhesive/sealant. • Versatile Installation Options - Suitable for use with Kerdi-Shower-T, -TS, and -TT prefabricated shower trays, as well as traditional mortar bed installations. • Long-Term Coverage - Backed by a 10-year limited warranty against manufacturing defects when installed per the Schluter Installation Handbook and Technical Data Sheet, following all guidelines and industry standards in effect at the time.
