This support frame for a wall-hung WC is designed with a specific height to accomodate the dimensions of the Island collection WC lid. It enhances the elegant, harmonious d�cor in the bathroom by allowing the built-in flush mechanism to be safely installed higher than standard and the lid to be perfectly aligned with the built-in cabinets in the collection. The frame is easy to install into the supporting wall and is compatible with the Island collection dual push-button flush plate (Ref. A8164880.., Ref. A8164890.. and Ref. A8900970..) and dual push-button (Ref. A8901900..) in the Baia collection.
