Replacement bonding flange for KERDI-DRAIN — the part that makes the waterproof connection between your drain body and the KERDI membrane. If you're replacing a worn flange or building a new shower with an existing ABS drain body, this is what you need.

The fleece-covered ABS flange bonds into thin-set mortar, and your KERDI waterproofing membrane overlaps onto it — creating a continuous waterproof envelope from the shower walls all the way into the drain.

• 2" ABS bonding flange for KERDI-DRAIN
• Fleece-covered surface bonds with thin-set mortar
• Connects to 2" ABS drain bodies via solvent cement
• Essential for maintaining waterproof integrity at the drain point

Pro Tip: The bonding flange is the single most important waterproofing connection in your shower floor. Don't rush this step — make sure the KERDI membrane overlaps the flange by at least 2 inches on all sides, fully embedded in mortar.
