Geberit’s Sigma70 dual-flush actuators feature smooth, seamless surfaces and a rimless design. To add or change the actuator cover, affix a rigid backer or material to the mounting bracket, tape and compress. They are available in easily-cleaned stainless-steel and glass finishes. The pneumatic actuator with light touch operation is supported by a lifter that acts like a rocker switch: touch on the left side to flush solids and on the right to flush liquids. The corresponding system is available for 2” x 4” and 2” x 6” installations.
