Geberit Duofix In-Wall Carrier for 2x4 Construction
Model: 111.798.00.1
The Geberit Duofix in-wall carrier system provides a strong, space-saving installation solution for compatible wall-hung toilets. Designed for 2x4 wood or steel framing, it conceals the toilet tank and plumbing inside the wall for a clean, modern appearance.
Its dual-flush Sigma concealed tank delivers either 1.6 GPF (6 LPF) or 0.8 GPF (3 LPF), helping reduce water consumption. The heavy-duty, powder-coated steel frame supports up to 880 lb (400 kg), while the insulated, impact-resistant HDPE tank helps prevent condensation.
