Geberit Installation System

Product Specifications

The In-Wall Duofix carrier system and Sigma concealed tank are designed for washdown wall-hung toilets, compatible with actuator flush panels or pneumatic push buttons. The system fits within a minimum 5 1/2" (146 mm) framing wall or plumbing chase. It requires wood or steel framing members spaced 19 3/4" (500 mm) apart, capable of supporting an 880-pound (400 kg) load without wall damage. The water supply line should have a minimum 1/2" (13 mm) copper tube diameter and a minimum flow pressure of 2 PSI (0.01 MPa).

The system is compatible with third-party listed, 2-hole wall-hung toilet bowls: 1.6 GPF (6 LPF) or 1.28 GPF (4.8 LPF) single-flush, and 1.6/0.8 GPF (6/3 LPF) or 1.28/0.8 GPF (4.8/3 LPF) dual-flush models. The carrier frame is adjustable for bowl rim heights ranging from 15" to 19" (381 to 483 mm). Actuator flush panels can be diecast zinc, molded plastic, or fabricated stainless steel. All components comply with applicable codes and product standards.
