Stacker for the 3rd level of the keyboard stands »Omega-E« 18800, »Omega« 18810 and »Omega Pro« 18820. The stacker is easily and quickly positioned to the desired height by a spring-loaded clamping knob. In addition, depth and inclination adjust in various positions. This stacker can only be used in conjunction with the 18811 stacker. A rubberised stop provides the necessary safety and prevents the keyboard from slipping.
