Design
Components
The rotary operating mechanisms consist of a masking plate with handle, including seal and fixing screws for door installation, an extension shaft (300 mm) and a coupling driver to be mounted onto the switch shaft.
The shaft coupling is only required if the 300 mm shaft needs to be extended by an additional shaft. Shafts with a length of 600 mm are also available as an alternative.
