Installation Versatility
This Sigma 12 cm support frame adapts to multiple wall configurations. Compatible with metal or wooden studs, it suits single-shell dry partitions, partial or full-height overlay walls, as well as full-height partition walls. Its design allows installation on screed with 0 to 25 cm height for wall-hung toilets.
Modular Design
The wall-hung toilet frame complies with EN 33 connection dimensions with a maximum projection of 70 cm. The lateral extraction plate mounts on metal profiles, wood, or Geberit Duofix studs at partial height. An alternative drilling allows direct wall mounting. Wide foot plates ensure optimal load distribution, complemented by integrated adjustment screws for precise alignment and galvanized feet for corrosion and slip resistance.
Optimized Connections
The adjustable 45 mm connection elbow enables tool-free installation with adaptable depth. Its rotating version offers a rear horizontal outlet pipe. Rear or top central supply is facilitated by an integrated sleeve for the Geberit AquaClean pipe and connection cable. The system includes an electrical mounting pre-equipment and a Power & Connect box.
