-KERDI-DRAIN ADAPTOR KITS  are used to convert traditional clamping ring drains to integrated bonding flange drains 
when removal of the clamping ring drain is not practical. A stainless steel adaptor ring with an overmolded rubber gasket replaces 
the clamping ring and is sealed to the existing drain body using Schluter
®
-KERDI-FIX. The bonding flange then slides into the adaptor 
ring and seals against the rubber gasket. Adaptor kits are suitable for both mortar bed and Schluter
